With the cold winter behind us and school finished for the year, it’s time to start thinking about getting our cars, trucks and SUVs ready for our summer road trip or vacation. Whether you have toddlers or teens, keeping everyone in the vehicle entertained during the drive will make the entire adventure much more enjoyable. Let’s take a look at some of the options available to keep your passengers happy as you rack up the miles this summer.
Rear Seat Entertainment Solutions
The classic road trip upgrade would be to have an overhead monitor or headrest monitors installed so your passengers can watch movies while you drive. The latest in a rear seat video solution is more of a computer than a TV screen connected to a DVD player. Many systems have video games built in and include wireless controllers. The games are not quite on the level of Fortnight or Minecraft, but they are still entertaining.
The majority of the headrest video systems available can be linked together so one unit can play a DVD on both screens. If you choose units that both include DVD players, make sure the headphones have at least two audio channels so passengers can listen to different soundtracks.
Another feature found on many new rear seat video systems is an HMDI input that is compatible with streaming solutions like Chromecast, Roku and Amazon’s Fire TV. If you have Internet connectivity, your options for entertainment are nearly unlimited. You can also connect a laptop or video game system to the screens. If you need a 120 VAC power inverter to keep that laptop charged or game system going, those are easy additions.
Headrest or Overhead Monitor Selection
There is no specific benefit or drawback to choosing an overhead monitor versus headrest monitors. Of course, with the overhead, everyone will have to watch the same programming. If the ages or interests of your passengers vary, though, this might not be the best choice. A large overhead monitor also can block the view from the rearview mirror when it’s folded down. Finally, in most applications, installing an overhead monitor requires permanent modification to the roof liner of the vehicle. If you leased your car or truck, you probably want to return the vehicle with the video system in place.
If you choose to go with replacement headrest monitors, make sure the units you choose are compliant with vehicle safety standards. Your headrests are fundamental components in preventing neck injuries if you have an accident. Your local specialist mobile enhancement retailer can help ensure the products you choose will keep you safe. Another consideration is that a headrest monitor is much easier to remove from a vehicle at the end of a lease than an overhead one.
Mobile Internet Connectivity
There are many ways to provide Internet access while on the road. We all seem to have cellphones with gigabytes of data access each month. Many smartphones will accept Wi-Fi connections from other devices, but if you happen to step away from the vehicle, the show stops. One solution is to have a mobile hotspot installed in your vehicle. Verizon, AT&T and Boost Mobile in the U.S. and Telus, Rogers and Bell in Canada offer portable solutions that work just like a wireless router in your home. Your kids can pair their tablets or computers to stream content to a video screen or play games with their friends over a high-speed 4G LTE connection.
Keep Your Smart Devices Charged
If you are using your phone for navigation, your better half is posting on Facebook and the kids are building landscapes in Minecraft, you will need a way to keep all of those devices charged up while on the road. There are numerous options for adding USB charging ports anywhere in the vehicle. Having a few high-current USB ports for your rear seat passengers negates the need to keep battery packs charged up and can tidy up a lot of wiring clutter. Your installer can wire the USB power ports to the vehicle ignition switch so there is no chance of the devices draining your car battery when the vehicle engine isn’t running.
Travel Safely and Efficiently
If you don’t have a navigation system built into your vehicle, you may want to consider one. Unlike the days of old, when maps from the auto club where the only way to help you get to your destination, modern navigation system provide detailed turn-by-turn directions. If you happen to veer off-course for a little sightseeing or make a wrong turn, the navigation system will update the route almost instantly to get you back on track.
In considering a navigation solution, there are two options. You can opt for a standalone solution like a Garmin, TomTom or Magellan product that sticks to your dash or windshield. While these solutions are reasonably priced, they add clutter to the vehicle’s interior and are dangerous in the event of an accident. The alternative is to upgrade your factory radio with a multimedia receiver with built-in navigation. Not only is the installation much tidier, but these advanced infotainment solutions also offer a lot more than just navigation.
If you are shopping for a new multimedia receiver, you will want to look at a solution that includes Android Auto and Apple CarPlay. These smartphone integration technologies work with the Google or Apple voice recognition system built into your smartphone to allow you to perform commands by talking to the radio. You can make phone calls, listen to incoming text messages, and dictate a response or check your voicemail. Both systems also include navigation systems that monitor traffic flow in real time to ensure you have the most-efficient route. Google and Apple are constantly updating their map data, so you’ll never need to buy a map update again.
If you happen to enjoy listening to podcasts or audiobooks, a multitude of apps for either platform will keep you entertained and informed.
A side benefit of an aftermarket source unit is that you can play digital media files and have built-in hands-free Bluetooth calling. Many source units offer multi-zone functionality that allows you to send video from the DVD mechanism to the monitor for the rear seat passengers. There are hundreds of options for source units, so drop by your local car audio specialist retailer and try some out on their display boards.
SiriusXM Satellite Radio
Although it may seem intuitive to those who already enjoy SiriusXM, satellite radio is a great source of entertainment while you drive. Unlike terrestrial radio that has a range of about 30 to 40 miles, SiriusXM uses a group of five satellites to broadcast directly to receivers all over North America. You can listen to the same broadcast in British Columbia, California, Newfoundland or Florida.
SiriusXM serves up more than 50 genre-specific music channels so you can home in on the music you like. Country, Alternative, Classic Rock, Rap and many more channels are there for your selection. There are also news, sports, comedy and religion channels to keep you informed and entertained. If it suits your fancy, the infamous Howard Stern is alive and well, broadcasting on SiriusXM Channel 100.
Adding satellite radio to your car, truck or SUV is easy, and several transportable solutions or products will integrate with a factory-installed or aftermarket radio.
Cruise in Style with Aftermarket Accessories
Most mobile electronic retailers can help you out with automotive lighting upgrades to make driving at night safer. A quality LED or HID bulb upgrade in the factory lighting system can make a world of difference. If you are looking for fog or driving lights, or maybe a reading light for the kids in the back, they can help with those as well.
If your car didn’t come with cruise control, an aftermarket system can be added relatively easily. Companies like Rostra offer kits for drive-by-wire and cable-controlled accelerator pedal configurations. If you have a Chevy Aveo, Pontiac Wave, Scion xA or xB, Hyundai Accent, Kia Rio, Ford Focus, Honda Civic, or Dodge Ram, cruise control kits for these and many more applications will make crossing the countryside much more enjoyable.
Get Road Trip-ready
Before you pack your bags, drop by your local mobile enhancement specialist retailer and talk to them about the entertainment and convenience options they have available to make your next adventure a lot more fun.

In a nutshell, a DSP uses a microcontroller that is designed specifically to manipulate audio signals in the digital domain. Pretty much all of the DSP devices on the market include crossovers, equalizers and signal delay features that we can use to optimize the performance of your sound system.
At the simplest level, a DSP can be considered a glorified yet extremely precise tone control. When you combine the features of a processor with measurements from a real-time analyzer, a properly trained technician can dramatically improve the tonal balance and accuracy of your audio system. Vocals and instruments will sound more as though you are in the presence of a live performance as opposed to listening to a recording. Expert technicians can use stereo equalization to improve the staging and imaging characteristics of your sound system, helping to increase the realism of the listening experience further.
Let’s continue with our three-way system example. In many systems, the tweeters are mounted at the top of the door, in the sail panel, in the dash or on the A-pillar. Midrange drivers in a system like that are typically 6.5 inches in diameter and are installed in the factory door location. Finally, woofers typically require an enclosure and are mounted in the trunk, cargo area or under the rear seat of a pickup truck. The distance between the listener and each speaker is different, as is the difference between the left and right speakers. These pathlength differences result in us hearing the closest speaker first, which makes our minds think that that is the source of the majority of what we are hearing.
Well, yes and no. Good quality processors start around $400 plus installation and require at least an hour to configure in most vehicles. If you have a complex multi-channel system, you may need a DSP with more input and output channels and additional time to configure the system in your vehicle.
If you are like most people, you may think that your local car stereo shop specializes in custom audio systems, speaker replacements and, if they have marketed themselves well, remote car starter installations. The reality is, many mobile enhancement retailers offer a variety of automotive enhancement services that extend well beyond 
Many new cars and trucks come from the dealership with advanced collision avoidance technologies. The most basic is a rear-vision camera system or parking sensor system that can alert you to the presence of an object or person while maneuvering your vehicle. If your vehicle doesn’t have a backup camera or parking sensors, a system can be added quite easily.
In the same vein as the parking sensors, an aftermarket blind-spot monitoring system will alert you to the presence of a vehicle or object beside or just behind yours. When an object enters this space, a small indicator will illuminate to alert you to an object in your blind spot. If you activate the turn signal, an audible warning will be produced to let you know that someone is there.
If you have an older vehicle or are interested in changing the look of your interior, your local mobile electronics specialist retailer can provide you with a complete custom interior. Companies like Katzkin, Leatherseats.com and Roadwire offer vehicle-specific seating upholstery in a variety of colors and patterns, including your choice of thread color. They can often embroider a logo into the upholstery if you wish. Many shops can also swap out the carpet in your vehicle with a new custom-molded piece in a variety of colors to complete the transformation.
Who better to install aftermarket 
A variety of new vehicles are still available without cruise control. Whether you have a classic car with a carburetor, a new vehicle with drive-by-wire throttle or something in between, aftermarket cruise control solutions are available to make your next long-distance trip a lot more comfortable.
Are you in the market for a set of side-steps, a new toolbox for the truck bed, a new tonneau cover or an off-road-ready grille guard? Drop by your local mobile enhancement retailer. In addition to being experts at automotive electrical systems, most shops have the tools and experience required to install a variety of truck accessories.
If you want to know where your vehicle or fleet of vehicles is at all times, a 
Do you have a power window that won’t roll down, a door that doesn’t lock when you press the button on your remote, or an intermittent instrument cluster? The advanced troubleshooting experience that most mobile electronics technicians possess far exceeds that of some dealership service centers. If there is something electrical or electronic not working on your vehicle, drop by and see if they can help.
If you live in a state or province that allows the use of radar detectors, the team at your local car stereo shop is far and away the best choice to integrate a premium system into your vehicle. Custom installed radar detectors and laser defense systems provide early warning against police radar and can delay laser measurement devices from obtaining a speed reading.
Having the windows of your vehicle tinted does a lot more than simply change the style of your vehicle. Window films block almost all of the ultraviolet energy from the sun to protect the occupants from accelerated skin aging. Premium films offer infrared rejection properties that help to keep the interior of your vehicle cooler. Window tint can also make your vehicle safer. If you get into an accident, the resulting tiny pieces of glass will remain adhered to the film rather than flying across the vehicle. Finally, window tint can help to reduce crimes of opportunity. If someone can’t see the contents of your vehicle, there is less reason for them to break in.
Many retailers offer automotive accessories like floor mats. One of the most popular brands in this category is WeatherTech. Their premium Floor Liner solution features a high-quality protective mat that is molded to the floor of your vehicle. The mat extends up the firewall and the center console to protect your carpet from damage, dirt and salt stains. WeatherTech also offers side window deflectors, mud flaps, bug deflectors and much more. Even if your local retailer doesn’t carry the WeatherTech brand, they should be able to source a solution to keep your vehicle looking great.
Are you looking for a set of lowering springs, a computer programmer or maybe a supercharger or turbo kit? Many mobile electronics retailers have technicians available to enhance the performance of your vehicle. A bolt-on exhaust, cold-air intake, high-flow air filter or throttle body spacer can provide your vehicle with a little extra power and may improve your gas mileage at the same time.
When it comes to creating an audio system that sounds amazing, incorporating a digital signal processor into the system gives your installer the tools required to compensate for the majority of the limitations that vehicles impose. To maximize the benefit, a digital signal processor system design needs to take the features and benefits of a processor into consideration. In this article, we are going to explain some of the key differences between a system with and without a digital signal processor.
A digital signal processor, also called a DSP, is an audio processor that uses a microcomputer to make adjustments to a signal in the digital domain. In a stand-alone processor, the audio signal from the source unit is converted to a digital data stream using an analog-to-digital converter. Once in the digital domain, the processor can equalize, filter and even delay the signal. Most processors have six or more output channels to provide us with the ability to send different signals to dedicated amplifier channels. Each channel has a digital-to-analog converter that provides a conventional analog audio output.
When you think of the stereotypical car audio system, most people imagine compact cars with large 
The monologue introduction to “Boom Boom Pow” by will.i.am builds to a crescendo from the 45-second mark, peaking with infrasonic information from :50 to 1:03. Content during this time extends solidly down to 7 Hz. There is another drop at 2:18, and the section from 3:13 to 3:42 contains a lot of infrasonic content. If your system is up to the challenge, this track has it all: a solid conventional bass line and enough content below 20Hz to make any true basshead happy!
Often referred to as Bass Check, “Hoods Run Down” by Lil Wyte is a rap song that starts with an introduction and the DJ plays five sequentially lower tones. The first is centered at 41Hz, and most factory sound systems can handle this one with no problem. The second “beat” is at 35Hz, and you are going to need at least a small sub to catch this one. The third drop is centered around 27Hz and will tax premium factory systems and aftermarket systems tuned to boom rather than rumble. Now things are getting fun! The second-to-last tone is centered at 20Hz and is going to be a workout for most vented enclosures. Pay attention; speaker damage may ensue! The last beat is centered around 16Hz. You are going to need serious cone area and power to feel this one with any authority. The rest of the song continues with a standard bassline with information around 30Hz. A good workout for your stereo and a nice gentle massage for the ride home.
Another classic rap track, “3 A.M.” features a steady bass line that extends down to around 30Hz, giving almost any sound system a chance to sound great. Interspersed randomly through the track are bass drops down to the single digits. There is lots of 9Hz content at the :57 and 2:01 marks. These don’t last long, but they are reasonably loud. You’ll hear 10-cycle beats at 0:37, 1:03, 1:54, 2:45, 3:11 and 3:37. There is lots of 50Hz content during these drops, so it might be hard to pick them out, but they are there.
This is more of a demo track than a song. Included on The Great Fantasy Adventure Album with main title themes from movies like Terminator 2, Clash of the Titans, Total Recall and The Abyss, “Jurassic Lunch” is a short 1:11 track at the end of the album. The track starts with birds chirping in the jungle. At the 13-second mark, a series of pulsations centered at 12Hz and 24Hz start. These continue to the 29-second mark, where harmonics are included that provide content above 30 cycles. It’s only then that you realize you are hearing the footsteps of the Tyrannosaurus rex stomping through the Jungle. Around the 39-second mark, you start to hear tree branches breaking with each step, and then at the 45-second mark, the roar of the Rex overpowers the track as he devours his prey. Of course, Kunzel included lots of bone-cracking and crunching around the 51-second mark. The Rex savors his meal from the 51- to 56-second mark, where he rewards himself with a giant burp that peaks with information down to 10Hz at the 59-second mark. This track serves as an awesome demonstration of a true subwoofer system.
This remake of “White Rabbit” by Jefferson Airplane features the required tuned PVC tubing percussion that has made Blue Man Group so unique. Though this track doesn’t share the intense infrasonic peaks of our other suggestions, it maintains an impressive level of 15-cycle content throughout the almost three-minute-long track. There is very evenly dispersed mid-bass energy in this track as well — a great challenge for your door speakers.
Another fun track from The Great Fantasy Adventure Album is the Terminator theme. This haunting track is full of special effects and mechanical sounds that remind listeners of the end scene of Terminator 2 as the machine slowly lowers himself into the mass of molten steel in the refinery. While most of the percussion comes from kettle drums in the 47-48 Hz range, the closing of the track features an explosion that starts at the 3:11 mark and peaks with 11Hz information from 3:14 to 3:16. A fitting ending to a great track.
This track goes back, waaaay back! Scholars think that Bach wrote this classic piece of organ music between 1704 and 1750 (when he died). Even those who don’t listen to classical music recognize this track. Don Dorsey released Bachbusters, a synthesizer-based take on some of Johann Sebastian Bach’s greatest pieces, in 1985. The album took first place on the Billboard classical music chart and has been popular with 
There had to be some dubstep in this list somewhere, right? “Centipede” is a somewhat creepy track that is full of fun bass. While the focus of the bass line is around 40Hz, the track contains content with good output levels down to the 10Hz range. While we doubt most clubs could reproduce this infrasonic information with serious output levels, the sensation of listening to this in a well-designed mobile audio system would be fantastic. It’s also really loud: The VU meters remain pinned at the 0dB mark for the majority of the track.
Another all-time-classic classical recording is Tchaikovsky’s 1812 Overture. This recording is known for its jaw-dropping cannon blasts at the end. When played back on a vinyl record, all but the very best turntable configurations will result in the needle jumping out of the track as the cannons go off. The first five cannon blasts appear at 12:36 into the track. The second and most impressive group begins at 14:41, with the blast at 14:55 containing low-frequency energy that extends down to nearly DC levels. Call it one to two Hertz if you want – it makes no difference.
“Purple Lamborghini” won a Grammy Award for Best Song Written for Visual Media. This rap track contains a bass line that is centered around 38Hz for the majority of the track. But the fun doesn’t stop there: Four times in the track, the bass sweeps from 50 down to 22Hz with impressive output. The video features Rick Ross, Skrillex and none other than Jared Leto in full Joker garb.
“Put On” makes our list with what we’ll call an honorable mention. The track doesn’t dig hard into the infrasonic region but contains four drops that repeat through the entire track. The first is up at 55Hz and is classic rap music bass. The second is at 44Hz and the third is at 36Hz, giving your body a nice massage. The last is centered around 27Hz and will give your subwoofers a good workout. We included this track because the 27Hz bass line appears no less than 22 times in this 5:21-second track.
The second of our three Honorable Mention tracks is “This Means War” by Avenged Sevenfold. This rock track opens with well-recorded percussion and guitar. At the 25-second mark, there is a rumble of thunder with great content down to 20 Hz that slowly fades to the 30-second mark. The remainder of the track only gets down to about 40Hz, but the kick drum is well-recorded and the entire track is well worth listening to.
Another honorable mention is Lorde’s “Supercut.” Though the main bass line remains focused between 40 and 60 Hz for the majority of the track, the section of the song from 2:34 to 3:05 has a surprising amount of information that extends down to 10 cycles at a moderate level.
Winning our “what the heck is that doing there?” award is “Supermarket Flowers” by Ed Sheeran. This track features Sheeran accompanied by a piano for the majority of the track. At the 2:08 mark, a synthesizer comes in to add some a gentle bass line to the track. The lowest notes are 28Hz at the 2:32 mark. While not the infrasonic content we were searching for, this remains a nice surprise in what would be described as a nice song.
