Leave the discs ashore
Tired of playing the same old scratched-up CDs every time you head out for a day on the water?

Bluetooth® for your boat

The KMR-M308BT works with all the latest gear, so you can keep the music playing all season long. Got an iPod® or iPhone®? You can plug your player (with optional cable) 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. The 13-digit LCD display makes it much easier to see song titles and channel information.
You can also connect to the latest SiriusXM tuner (sold seperately, subscription required) and enjoy your favorite music, sports, and entertanment programs on the water, whether you're on an inland waterway or up to a hundred miles offshore.
If you store your music on an Android device, Kenwood's Music Control app allows you to enjoy a variety of search and playback features when your phone is plugged into the front-panel USB.

- 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.
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).
Preset EQ: Eight EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music. Each preset has its own level settings for bass, midrange, and treble . You can choose from the following preset EQ curves; Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User. 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 Bass (200Hz) , Midrange (2.5kHz), and Treble (12.5kHz) level from +/- 8dB.
Sound Enhancements: The head unit provides further sound enhancements for your car audio system.
- Bass Boost: The Kenwood receiver features a Bass Boost control that can be set to the following levels (BB1, BB2, BB3, or Off).
- Loudness: This function enhances low and high frequencies to make the sound clearer lower volumes. There are 3 levels (LV1, LV2, 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).
Key Beep: The marine head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

Works as advertised. Fits nicely in my Woody's fairing on my HD Heritage Softail. Powerful enough I can hear tunes via 4 5" speakers even with Vanes and Hines pipes.
