The Momento M6 smart dashcam continues the evolution of amazing features and performance that drivers have come to expect from Firstech. Equipped with a Wi-Fi hotspot that works with an app on your smartphone, downloading videos from the M6 is as easy as tapping a few icons. Read on to learn more about the features and technologies integrated into this impressive safety camera system.
Features of the Momento M6 Dashcam
The M6 is the smallest of the Momento dashcams, measuring a mere 89 x 43 x 29 mm (3.5 by 1.7 x 1.15 inches). This size reduction comes with the elimination of the LCD screen on the back of the camera (as found on the Momento M5 and M4). Instead of the screen, Momento includes a Wi-Fi hotspot and dedicated mobile applications for iOS and Android smartphones that allow you to view the camera image in real time, download and edit videos for direct upload to social media and configure the resolution, motion sensor and battery cutoff settings for parking mode. Even if you’ve parked your car or truck in the driveway, the Wi-Fi connection works as far as 10 meters away to allow you to download videos from inside your home.
Along with access to all the video files stored on the memory card in the camera, the app includes a driving data and travel log screen that shows mileage, trip time and impact event information.
An integrated GPS antenna captures vehicle location and speed information and stores that along with the video file. The adjustable impact/motion sensors can be set to trigger event recordings that start 15 seconds before the trigger and end 15 seconds after. Both cameras record in full-HD 1920×1080 resolution at 30 frames per second and provide excellent low-light performance and detail, thanks to the Sony Exmor R image sensors.
Momento backs the M6 (also known as the MD-6200) with a two-year warranty.
Momento includes a 32GB micro-SD memory card to get you going, and the system is compatible with Class 10 cards up to 256GB. It is worth nothing that you must use a specific formatting method with 128GB or 256GB cards for them to work with the M6. You can find information on the large-capacity card requirements at https://support.momentocam.com.
Rear-Facing and Optional Interior Cameras
The M6 (known formally as the MD-FC6200) includes a secondary camera called the MD-RC6200. Your installer can mount this camera in your rear window. Both the front and rear cameras include 135-degree wide-angle lenses to deliver an amazing 270 degrees of surveillance coverage.
If you operate a taxi or a ride-sharing service like Uber or Lyft, the optional MD-IC6 interior camera is a perfect upgrade. The IC6 replaces the rear-facing camera with a unit designed to record the interior of the vehicle. 
Integrated infrared LEDs provide illumination, so even on the darkest of nights, the recording is clear and easy to see. If you’re concerned about theft or vehicle damage from unruly clients, the IC6 is a great option.
Parking Mode
Just like the M5 and M4 cameras, the M6 includes a parking mode. Once you park your vehicle and turn off the ignition, the camera will continue to monitor the area in front of and behind your vehicle for motion. Should it see someone or something move into the image area, it saves a video file from 15 seconds before the trigger to 15 seconds after the event. Likewise, the onboard shock sensor can trigger a recording. If you want to see which pesky cat is walking on your car’s hood in the middle of the night, the Momento M6 is the answer.
As alluded to earlier, parking mode automatically shuts down when the vehicle battery voltage reaches a preset level, so you’ll never be left stranded.
Protect Yourself with a Momento Dashcam
Whether you’re concerned about staged accidents at stop signs and intersections or want to capture those “I can’t believe he just did that” driving events that happen almost every day, equip your vehicle with the Momento M6 dashcam system. Visit your local authorized Momento dealer to find out more about installing a dashcam system in your vehicle.

Beyond the features and design of a subwoofer, no single factor affects the performance of a subwoofer system more than 
As you can see, above 60Hz, the smaller enclosure is a little bit louder but remains within a decibel or two. Below 50Hz is where things start to vary more. The larger enclosure is 2.15 dB louder at 35Hz and 3.35 dB louder at 25 Hz. While it might not appear dramatic, 3dB is the equivalent of having twice as much power driving the subwoofer. However, this increase in efficiency comes with no thermal power handling penalty.
Once again, above 60Hz, there is minimal difference in the excursion between the two drivers. Below that, the larger volume of air in the big enclosure has less effect on the stiffness of the subwoofer system. The result is the subwoofer moves farther for each watt of power. If you compare the excursion graph to the frequency response graph, the efficiency levels are directly correlated.
The second popular option for a subwoofer enclosure is a 
Now, while most vented enclosures are larger than their sealed brethren, the benefit is often an increase in output that is potentially more than having two subs in a sealed design. In fact, this vented design is louder from 20 to 60Hz than three identical subs in an enclosure that is 50% larger (1.8 cubic feet).
This reduction in cone excursion increases physical power handling and also reduces distortion – as long as you have designed and constructed the vent properly. Vents need to have a large enough area so that air velocity in the vent is kept to a minimum. The mouth of the vent also needs to have a large radius
Bandpass enclosures are called that because they not only act as a high-pass filter but as a low-pass filter as well. A typical bandpass enclosure features two chambers. The woofer is mounted between these chambers. In a single-tuned enclosure (often referred to as a fourth-order bandpass or single- reflex bandpass), one of the chambers includes a vent from which all the sound is created. A benefit of this design is the ability to feed that vent through an opening in a rear parcel shelf or similar to ensure coupling with the interior of the vehicle.
The second bandpass enclosure design is a Double-tuned design where both the front and rear chambers are vented. In a Series-tuned bandpass enclosure, the large rear chamber vent feeds into the front chamber. In a parallel-tuned design, the vents from each chamber feed directly into the listening area. Double-tuned bandpass designs are often referred to a sixth-order or dual-reflex designs.
A quick note on “basic” subwoofer systems. Over the years, we’ve seen a LOT of retailers offer “bass packages” that include a sub, amplifier, enclosure and often a wiring kit. In the majority of these packages, the retailer has paired an inexpensive sub with an inexpensive amp and a sealed subwoofer enclosure to minimize the total cost of the system. When you are limited in 
No single upgrade to an audio system offers a larger improvement in sound quality than the addition of a 
In the simplest of terms, a subwoofer is a large speaker designed to play frequencies below 100 Hz at relatively high output levels. Subwoofers are most commonly available in 10- and 12-inch sizes, but 6.5-, 8-, 13.5- and 15-inch subs are also readily available.
Picking “enough” subwoofer depends on several factors. How loud is loud enough? How much space can you afford to give the subwoofer system? How powerful of an amplifier can your vehicle’s electrical system support? It can be difficult to choose the right sub based on these criteria, especially since different vehicles offer different amounts of cabin gain. Would a single 10-inch sub in a sealed enclosure in the back of a Honda Fit be a suitable solution in a Cadillac Escalade or short-cab Ford F-150?
The next step is to decide 
If you want something truly unique, then ask about including LED lighting in the enclosure. You can choose to have a Lexan or Plexiglas window added and illuminate the interior of the enclosure or add acrylic plastic accent pieces that light up. Upgrades at this level are often combined with enclosures finished with multiple materials – different colors of vinyl can provide amazing cosmetics.
The next step, beyond a simple wooden 
Companies like JL Audio, MTX and Kicker offer subwoofer systems designed for specific models of vehicles. These enclosures are designed to offer impressive performance while minimizing how much space they use. Some companies construct these enclosures from fiberglass in large molds, while others use thick plastics. In most cases, while these enclosures are visible once installed, they are available in materials that match the color of the vehicle interior. An application-specific enclosure is a great way to add amazing bass to a vehicle quickly and efficiently.
You’ll note that we haven’t discussed the specific features of subwoofers that differentiate one from another. This omission is quite deliberate because we will dedicate an entire article to that topic. In the meantime, it is worth discussing the difference between a conventional subwoofer and a shallow-mount design.
When it comes to designing 
Up until recently, most recording studios used a pair of high-quality 
There are lots of ways to describe the experience of having the music come from all around the vehicle, but the analogy of a nightclub or – as we old fogies like to call them – a disco might work best. The concept here is that the music will seem to come from all around you. Unlike a performance where you can point to the source of sound from each instrument, it envelops the listening space. In most of these systems, we still balance the system with dedicated left and right channels.
You may have noticed that we haven’t talked about a live performance that takes place in a concert hall or indoor venue. This has been quite deliberate.
Another option is to use a signal processor to create a sense of room size. In the 1990s and 2000s, lots of processors had presets for jazz, concert and club settings that added reverberation and delay to dedicated rear channel outputs. These technologies have evolved to more-advanced processing algorithms like Bose Panaray and Quantum Logic Surround from Harman. These systems can analyze the content of a stereo recording and extract information that should be reproduced by side and rear speakers to create an immersive listening experience. If your vehicle has one of these technologies, your 
Just as the invention of the transistor eliminated the need for vacuum tubes, advances in technology allow us to create new and unique entertainment solutions with more and more features. We thought it would be fun to take a quick look at a few important 
The first car 
Radio was truly the technology that drove 
Reel-to-reel recording on magnetic tapes was popular in the 1940s but wasn’t suitable for use in mobile applications. The 8-track was preceded by the Stereo-Pak 4-track cartridge in 1962. The endless-loop cartridge could store both sides of a vinyl album. The 8-track, known originally as the Lear Jet Stereo 8 Track Cartridge, was launched by Bill Lear in 1963. In 1965, Ford offered factory and dealer-installed 8-track options on its Mustang and Thunderbird and on several high-end Lincoln vehicles.
Most people don’t realize that digital audio (known then as pulse code modulation) was invented in 1937 in Britain and was used in telecommunications. In the late ’60s, Denon pioneered commercial digital recording. The BBC used digital audio transmissions to link its broadcast center to its transmitter in 1972. Sony and Mitsubishi drove the consumer popularization of digital audio in the early ’80s and brought about acceptance by major record companies. The first compact disc was released in 1982 using the Red Book Compact Disc Digital Audio (CD-DA) standard that is still in use today. The first OEM-installed CD players were in the 1987 Lincoln Town Car.
The benefit of Class D amplifiers is their efficiency and low-to-moderate power levels. Class D amps use high-frequency pulse-width modulation waveforms to switch MOSFETs (metal-oxide-semiconductor field-effect transistors) on and off very quickly to amplify signals. Filter networks on the output of the circuits remove high-frequency noise so that only the audio signal is left to drive our speakers. Class D amplifiers allow manufacturers to produce much more powerful amplifiers that take up very little space. These amplifiers consume less current than their Class AB counterparts.
The Apple iPod was introduced in the fall of 2001. The original compact digital media players were only compatible with computers running the Apple Macintosh operating system and as such, sales were limited. In 2003, the iPod 3G was launched with a standard USB port instead of Firewire, making it compatible with Windows-based PCs as well. By June 2003, Apple had sold 1 million iPods.
Though incorrectly perceived as a hands-free and audio streaming technology, 
Since the very first car radios were built, people were concerned about them being a distraction. Turning the tuner knob to find a local station meant you weren’t focused on the road in front of you. In the late ’90s, we saw drivers with headsets and earpieces making phone calls while they drove. Adding a headset was a common purchase with a new phone. In the mid-2000s, Bluetooth communication replaced wired hands-free connections.
