No discs required
No discs required
Leave those discs on the dock. Kenwood's KMR-M312BT digital media receiver lets access the music on your phone, iPod, or other portable device when you head out onto the water. This marine-rated receiver will withstand the harsh marine environment, and its 4" deep chassis also makes it a great choice for ATVs, side-by-sides, golf carts, and other applications where a regular CD player really isn't an option.
You can connect up to six wired remotes to this Kenwood receiver.
Great with Apple or Android
The KMR-M312BT works with all the latest gear, so you can keep the music going all season long. Got an iPod® or iPhone®? You can plug your player into the front-panel USB input to access your playlists. Dedicated "search" and "return" buttons, plus handy tools like AppMode, Alphabet, Percentage Skip, and Related Search, help you find your music fast. You'll also be able to use Siri® Eyes Free control capability with a compatible iPhone.
If you store your music on an Android device, you can connect and control your phone using the front USB port or the receiver's built-in Bluetooth. You'll be able to run the apps you like and take advantage of a variety of search and playback features. Hands-free calling is another Bluetooth benefit that's sure to please any captain.
You don't have to rely on your phone for entertainment, however. You can liven up your cruise by plugging in a thumb drive or jacking another device into the front-panel aux input. The KMR-M312BT can play MP3, WMA, AAC, WAV, and FLAC music files, so you'll be able to enjoy your entire library. The variable-color 1.5-line LCD display makes it easy to see song titles and channel information, even when you're blasting through choppy water.
The centerpiece of your system
You can connect up to six optional Kenwood marine remotes to control the KMR-M312BT from anywhere on your boat. And, if you're a satellite radio fan, add a SiriusXM tuner (subscription required) to enjoy all your favorite music, sports, and talk, even when you're miles offshore. This Kenwood features three sets of preamp outputs, so you'll be in good shape when you decide to add marine amplifiers to your system.

Marine, Display, & Remote Features
Marine Rated: The Kenwood KMR-M312BT marine receiver has a special water-resistant conformal coating placed on its main circuit board to protect its circuitry from the harsh, corrosive marine environment. Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover such as the Metra (120999005B, sold separately) or Scosche (142ACM1, sold separately).
Detachable Face: The Kenwood KMR-M312BT features detachable face plate to deter theft. There is no protective face case included. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

Audio Section
16 Bit D/A Converter: The Kenwood KMR-M312BT utilizes a 16-bit digital to analog converter for superior sound quality.
MOSFET Amplifier: The Kenwood KMR-M312BT 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 KMR-M312BT are as follows:
- Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
- Maximum Output Power: 50 watts x 4 channels
6ch/2.5V Preamp Outputs + Sub Control: The KMR-M312BT features front, rear and subwoofer 2.5-volt preamp outputs. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading. The Kenwood KMR-M312BT offers the following subwoofer controls, when you are using unit's subwoofer preamp output.
- Low Pass Filter: The receiver features a built-in Low Pass Filter control for the preamp-output, when the output is set to Subwoofer. You can select from 85 Hz, 120 Hz, 160 Hz, or off.
- Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
- Subwoofer Level: Once the Subwoofer preamp output is activated, you can independently control the subwoofer preamp output level (-15 to +15) from the digital media receiver.
Front & Rear High-Pass Filter: The KMR-M312BT features a High-Pass Crossover for the front & rear channels when your front & rear speakers are connected by the unit's speaker-outputs or preamp-outputs. You can adjust the high-pass crossover from "Through", 100, 120, or 150 Hz. The "Through" selection is a full-range setting.
Speaker Settings: The Speaker Setting function tailors the head unit's audio settings according to the type of speakers in your vehicle. You may select a Speaker Setting of 'SP-Off' (flat/off), 'SP-OEM' (for OEM factory speaker systems), 'SP-6x9/6' (for systems with 6" and 6"x9" speakers), or 'SP-5/4' (for systems with 4" and 5" speakers).
EQ Pro: The KMR-M312BT is equipped with Kenwood's EQ Pro. The integrated equalizer offers 8 preset sound modes (Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User) suitable for the music genre of your choice. The Drive EQ mode is an EQ preset that helps reduce road noise. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).
EQ Pro | |||
---|---|---|---|
Frequency | Level | Q | |
Bass | 60, 80, 100, 200 Hz | -8 to +8 | 1.0, 1.25, 1.5, 2.0 |

- Bass Boost: The Kenwood digital media receiver features a Bass Boost control that can be set to the following levels (1-3 or off).
- Loudness: This function enhances low and high frequencies to make the sound clearer lower volumes. There are 3 levels (1-2 or Off).
- Sound Reconstruction: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.
- Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0 (-8 to +8 for Aux source).

This radio is great! I bought it for my Harley Ultra along with Biketronics installation kit. It works excellent. I have only had it in a couple weeks, but I haven't had any problems.
