About the JVC KD-X38MBS

Equipped for outdoor rockin'
Equipped for outdoor rockin'
JVC's marine-rated KD-X38MBS digital media receiver is outdoor-ready, thanks to a conformal-coated circuit board that resists moisture damage. And its white-background display cuts through glare and makes this receiver ideal for open-top vehicles. With built-in Bluetooth®, an option for satellite radio, and plenty of connections for your digital devices, you'll have lots of music options on the road, trail, or water.

The display's white background provides more visibility, even against the sun's glare.
Bluetooth for wireless convenience
Bluetooth is the norm for wireless phone functionality these days. The KD-X38MBS lets you pair two Bluetooth-equipped phones and quickly switch between them for hands-free calling. You can wirelessly stream and control the playback functions of just about any Internet radio service, including Spotify, TIDAL, and Qobuz. You can also stream stored music, audiobooks, and podcasts from the phone that's active. JVC also added a little fun to audio streaming with their Streaming DJ feature — pair five phones so everybody can pick their tunes for the ultimate road trip playlist (don't forget to share). Bluetooth also lets you control this stereo directly from your iPhone® or Android™ phone by downloading Kenwood's free Remote app.

Media on the go
You can play and charge your iPhone or check out a USB drive filled with digital music through the front USB port. Android users, you can control and play music using Bluetooth. JVC rounds out the connectivity with a front aux input for a portable music player. You can also expand your entertainment options by connecting a SiriusXM satellite radio tuner (sold separately) and listen for days without losing your favorite channels.
Tweak your system...
The KD-X38MBS plays MP3, WMA, AAC, WAV, and even high-res FLAC files, and you can make the most of them with a wide array of sound-shaping tools, including digital time alignment to ensure you're center stage, Sound Lift to raise your music from depths of your doors, and a 13-band graphic equalizer to put the emphasis where you want it in your music. If you're planning to expand your audio system in the future, the KD-X38MBS includes three sets of ultra-clean 4-volt preamp outputs for adding amplifiers to power high-quality speakers and subwoofers.
... and customize the look
This receiver includes 2-zone variable color illumination, so you'll get to dial in your look with two different colors on your JVC face. You can even sync the lights to match your music.

Marine & Remote Features
Marine Rated: The JVC KD-X38MBS marine receiver has a special water-resistant, anti-rust conformal coating placed on its main circuit board to protect its circuitry from the harsh, corrosive marine environment of boating and the outdoor elements of motorsport. A conformal coating is a protective chemical coating to safeguard electronic circuits from harsh environments that may contain moisture or chemical contaminants. It provides a barrier to airborne contaminants from the operating environment, such as salt-spray, thus preventing corrosion.
Note: Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover (sold separately - see Accessories Tab) for further protection against the harsh outdoors and marine environment.
Remote Control Options: The JVC KD-X38MBS offers support for JVC's marine wired remote control and 3rd-party steering wheel control adapters (all sold separately).

Audio Section
24 Bit D/A Converter: The JVC KD-X38MBS in-dash digital media receiver utilizes a 24-bit (DAC (digital-to-analog converter) for superior sound quality.
MOSFET Amplifier: The JVC KD-X38MBS is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KD-X38MBS are as follows:
- Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)

This was my first car stereo install/replacement! The products/tools provided worked great. The prepared wiring harness made the job quick and simple. I wouldn't hesitate to attempt this again. This was a great experience. I'll absolutely look at Crutchfield first for any vehicle audio needs.
