When it comes to recreating music in our cars, the weakest link in the chain will be the downfall of the entire system. Knowing this, if we start with the best recordings possible, the chances of our music sounding more realistic and lifelike increase astronomically. The equipment required to record, master and distribute high-resolution music helps to ensure that our mobile entertainment systems sound amazing.

What Is High-Resolution Music?

By definition, any music that is recorded with a bit rate (sampling rate) and bit depth (resolution) higher than that of a compact disc is considered high-resolution. This means 48 kHz and higher sampling rates and 24-bit resolution are required. Higher sampling rates capture some harmonic information, but transmitting and reproducing those sounds is extremely difficult.

Where Can I Get High-Resolution Audio Files?

Perhaps the best-known source for high-resolution music is hdtracks.com. This website rightly boasts that it has the widest collection of high-resolution music available. You have a choice of purchasing and downloading albums in AIFF, ALAC, FLAC and WAV formats at resolutions up to 192 kHz/24-bit as well as 2.8 MHz and 5.6 MHz DSD files. File formats vary by album.

Another popular source for buying high-resolution albums is Acoustic Sounds. Acoustic Sounds Super HiRez specializes in DSD format. The itrax.com website is another great source.

If you’re into streaming, you will definitely want to check out Tidal.com and Qobuz.com.

Why Should I Buy High-Resolution Music?

Some people will tell you that humans can’t hear audio above 20 kHz and that we don’t need more than 16 bits of resolution to accurately recreate a listening experience. Let’s say these statements are completely accurate. Why then would we want to buy high-resolution music? The answer is noise and accuracy.

The effort required to build a microphone that records to 40 or 50 kHz requires serious attention to detail. Capturing the upper end of the audible range is child’s play for products of this caliber.

The second benefit of high-resolution recording is a reduction in noise. This reduction comes from the fact that there’s an increased number of bits to work with (65,536 vs. 16,777,216) and the fact that the equipment used must be of a higher performance specification. Digital interfaces capable of working with high-resolution microphones from companies like RME, Presonus, Apogee and Focusrite deliver amazingly accurate digital conversions of the analog signal from the microphone. If you’re a numbers geek, as many of us are, here are some specs from the best studio-quality interfaces:

Frequency Response: 2 Hz to 92 kHz at -1 dB
Signal-to-Noise Ratio: 113 dB unweighted
Total Harmonic Distortion: <0.00032%
Channel Separation: >110dB

How to Reproduce High-Resolution Audio in Your Car

Buying great music is one thing, reproducing it in a vehicle is another challenge. Companies like Audison, Sony, Brax, Zapco and Kenwood all make audio components that will output or process high-resolution audio file formats. Of course, to hear that level of detail, you’ll need amplifiers capable of playing to at least 40 kHz and speakers with similarly impressive specifications.

Finally, and most crucially, how these components are integrated into your vehicle is also very important. To make the best use of the high-frequency information audible from high-resolution recordings, your tweeters will need to be mounted on-axis with the listening position or bounced off the windshield from a dash-mount location. If not, the directivity characteristics that are inherent in every speaker will make those sounds inaudible.

Many new cars and trucks come with a feature called stop-start technology. This system senses when the car is stopped at a red light or stop sign and shuts down the engine to save fuel. As soon as you release the brake pedal, the engine starts up again, and you’re on your way. The question for those of us who are interested in upgrading our vehicles is, does this technology work with our new electronics? Read on to find out if your new high-power amplifier, dash camera or radar detector will get upset when your car stops and starts.

How Does Stop-Start Technology Work?

Almost all new cars are controlled by computers. As such, the act of turning off your engine at a stop light is as simple as cutting spark to the ignition system and fuel injectors. To restart the car again, the vehicle initiates the start-up sequence as though you pressed the start button on the dash. The radio keeps playing, the climate control system keeps running and all the lights stay on while the engine is off. Other than an eerie silence and a split-second hesitation when it’s time to drive off, you don’t really notice anything.

In the background, the computer in your car is monitoring several systems to determine when it should stop the engine and when it needs to start it again. If it’s summer and you’re running the air conditioning, the computer will monitor the temperature in the vehicle. If it starts to warm up, it starts the engine so the compressor can run. If it’s winter and you have the heated seats and rear window defroster running, the system pays close attention to the current draw on the battery and its voltage. Brake pedal pressure, the position of the clutch (if you have one), engine coolant temperature, a buckled seat belt and many other conditions determine whether the engine will stop at a light and when it will restart.

What’s the Problem with Stop-Start Systems?

While saving fuel seems like a great idea, there is a drawback to this system in terms of aftermarket electronics in your car. When the engine starts, there is a large draw from the vehicle battery. In some cases, the battery voltage can drop well below 9 volts. For many years, electronic devices designed for use in cars had a low-voltage cutoff around 10.8 volts. In cases where the voltage drops into the 9V or less region, your amplifier, signal processors, source unit, dash camera or radar detector may shut down, then restart once the voltage increases. If the voltage drop is extreme, problems with the microcontrollers in your devices may occur.

Dealing with Stop-Start Vehicles

If you own a vehicle equipped with one of these fuel-saving technologies and are interested in adding aftermarket electronics, search for a specialist mobile enhancement retailer who is familiar with how they operate.

For low-power devices like signal processors, radar detectors, laser jammer and dashcams, voltage stabilization modules are available to help keep everything happy. Companies like ARC Audio design their new amplifiers and processors to handle these low-voltage conditions. Audison offers a product called the ES3 that will help maintain voltage to certain low-power devices. Work with your salesperson to choose products that list stop-start compatibility in their feature list.

You will also want to make sure that the battery or batteries in your vehicle are in good condition. Even after a few years of regular use or in even harsher conditions involving multiple short trips, batteries can build up a layer of sulfate on their lead plates that can dramatically reduce their current delivery efficiency. A high-quality battery charger with maintenance capabilities can be a great investment in maintaining the life of your batteries and, of course, will ensure that your vehicle is ready to go whenever you are. Some companies offer maintenance chargers specifically for start-stop batteries.

Choose Your Technology Upgrades Wisely

If you’re thinking about upgrading the technology in your new car or truck that has stop-start technology, visit your local specialist mobile enhancement retailer and ask them about the solutions they have available.

With the rise in popularity of digital media files over the last decade, car audio enthusiasts find themselves being more likely to carry a USB memory stick than a stack of compact disks. When it comes to organizing all those MP3, WMA, AAC and FLAC files, most manufacturers suggest that you don’t put all the songs in one folder. Read on to find out why.

How Car Radios Understand USB File Structure

Unlike a computer, your car radio is very limited in its ability to interpret different USB drive formats and the subsequent file structure. Most systems require that the USB drive be formatted using the FAT or FAT32 file format. Some new multimedia receivers can understand NTFS and exFAT file formats, so larger storage devices can be used.

Next, you need to maintain a standard long file name format that allows for a total of 255 characters, including the file extension (.mp3, .wma or .flac). An important part of the standard is avoiding command characters such as /, \, *, :, ?, “, <, > and|. These characters may be misinterpreted by the system and result in a file being unreadable, or on extreme cases, cause the system to stop reading subsequent filenames.

Folder Structure and File Limits

In most cases, you are limited to no more than eight folder layers. So, beyond the root folder, you may have subfolders by genre of music, artist name and album name. This configuration is fine as the music is stored four layers deep. It is worth noting that extremely long folder names may, depending on the radio and its available memory, cause problems. We recommend keeping everything as short and efficient as possible.

Different source units have significantly different limits on the total number of tracks they can play and the number of files or subfolders they can interpret. Many radios have a limit of 255 or 999 files or folders per directory and can only detect up to 999 files. Some radios increase this to 5,000 or 9,999 tracks. A few units on the market can read an impressive 65,535 files per folder, and there are a couple with supposedly no limits at all.

Don’t Put All Your Files in One Folder

When you are planning on buying a new radio, it’s worth spending a few minutes to find out whether it will play your music as you have it organized on your USB stick. Some radios won’t randomize songs in different folders, and others are extremely finicky about the total number of files. If you need help choosing a receiver that will sound great and play your digital media collection, drop by your local specialist mobile enhancement retailer and give the radio you have in mind a try!

Hybrid and all-electric vehicles are a great platform for stereo system upgrade. While your local specialist mobile enhancement retailer can’t tap into the main battery pack, the electrical system on these cars or trucks is more than adequate to power an amplifier to drive new speakers or a subwoofer. There are several options for upgrades and accessories that can transform your vehicle – let’s check them out.

Limitations of Factory Sound Systems

As with most new cars and trucks, the limiting factors in the performance of the factory audio system are weight and cost. While companies like Harman, Bose, Bowers & Wilkins and Rockford Fosgate are more than capable of delivering listening experiences that can rival a live performance, they are limited by the budget for each vehicle and the amount of weight that can be added. Weight negatively affects the handling, braking, acceleration and fuel economy. That results in audio systems that sound acceptable, but not great.

Upgrading Hybrid and Electric Vehicle Stereo Systems

In almost every case, adding a subwoofer to your car or truck will make the biggest impact on the overall performance of the sound system. Right now, look at the bass setting on your car radio. Is it turned up? Even one or two notches require the factory radio and speakers to work a lot harder. Imagine if you could turn the bass down and dedicate an amplifier and speaker to reproducing low-frequency information. Your speakers will sound better and the overall system will be more lifelike, play louder and deliver better clarity.

Subwoofer systems come in all shapes and sizes, from compact solutions designed to fit into the corner of a cargo area to unique cylindrical subwoofers that fit inside a spare tire. These all-in-one bass upgrades offer great value.

If a product isn’t already available for your vehicle, talk to your local specialist car stereo shop about building a custom solution. The salesperson and installation team can design a solution that uses one of the many shallow subwoofers available to create an enclosure that fits your vehicle perfectly and delivers amazing bass.

DSP and Speaker Upgrades

Modern audio systems often include incredibly advanced system tuning, and many vehicles include a center channel with an upmixer to ensure that the sound delivered to every seat in your vehicle sounds great. Understanding how to work with these systems and incorporating a digital signal processor requires specific training and experience. Make sure the shop you choose to work on your vehicle understands your needs and the complexity of these factory systems before they dive in.

Speakers are, without a doubt, the most important aspect of any audio system. Imagine spending thousands on a home audio CD transport, a stand-alone DAC and an amazing amplifier, only to connect a set of speakers that your uncle or cousin rescued from bulk recycling day. Upgrading the speakers in your vehicle with something truly awesome, then re-tuning the system with a signal processor to work with those new speakers, is a truly night-and-day experience.

Can I Upgrade the Radio in My Hybrid or Electric Vehicle?

In almost every case, the answer to “Can I upgrade my radio in a hybrid or electric vehicle?” is no. Does this mean you can’t upgrade the audio system? Not at all. Many companies make interfaces that are designed specifically to work with factory-installed source units to make adding amplifiers and new speakers easy and reliable.

Choose Your Installer Wisely

Upgrading the audio system in a hybrid or electric vehicle isn’t much harder than in a conventional gasoline or diesel-powered car, truck or SUV. With that said, be sure that you choose a mobile enhancement retailer who is knowledgeable about the requirements for your specific vehicle and has the training to deliver the results you want.
