Made for marine use

If you enjoy listening to music on your boat, you need a receiver that's built to handle the extemes of the marine environment. Kenwood's KMR-555U marine receiver features a conformal coating that keeps moisture out of the internal circuitry, plus covers to keep spray out of the USB port, auxiliary input, and CD slot.

Enjoy your digital media

The KMR-555U is ready to work with all the latest media options, so you can keep the music playing 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, make it easy to find your music fast. The big 3-line display makes it much easier to read multiple lines of scrolling text.

Pandora® control and Android compatibility

If you're an iHeart Radio® or Pandora® Internet radio user, you can listen to your favorite stations when your iPhone's connected. If you store your music on an Android device, Kenwood's free Music Control app allows you to enjoy a variety of search and playback features when your phone is plugged into the front-panel USB. This receiver also offers a rear USB port, so you've got plenty of connectivity options.

Even more options

You can also liven up your cruise by loading in a disc full of music files, plugging in a thumb drive, or by jacking another device into the front-panel aux input. Add up to three Kenwood KCA-RC55MR or seven KCA-RC35MR marine remotes to the receiver, and you can control it 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. The KMR-555U features 3 sets of preamp outputs for marine amps and subs, plus a 3-band equalizer that helps to optimize audio performance.

    Audio Section

    24 Bit D/A Converter: The Kenwood KMR-555U utilizes a 24-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The Kenwood KMR-555U 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-555U 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: The KMR-555U 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 front, rear, and subwoofer preamp outputs are fixed to the rear chassis of the head unit.

    Note: You can turn the head unit's built-in amplifier off to improve the quality of the sound from the head unit's preamp outputs.

    Front & Rear High-Pass Filter: The KMR-555U 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.

    Subwoofer Controls: The Kenwood KMR-555U 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 CD 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 (100Hz), midrange (1kHz), and treble (12.5kHz). You can choose from the following preset EQ curves - Rock, Pops, Easy, Top 40, Jazz, Natural, Game, and User.

    Note: You can store bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB, iPod, and Pandora).

    Bass Boost: In addition, The Kenwood CD 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).

    Supreme Setting: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting 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 the Supreme Setting 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 in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Display Illumination/Clock Display: When the unit is in Standby mode, the face and button illumination is "keyed." When the Clock Display is turned on and the unit is in Standby mode, the Clock Display is also "keyed." Pressing and holding the source button turns the unit off completely.

    Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.

    Remote Control

    Optional Wired Remote: The Kenwood Marine KMR-555U CD receiver is compatible with Kenwood's add-on marine wired remote controls (sold separately).

    • LCD Marine Remote: The Kenwood KCA-RC107MR or KCA-RC55MR add-on marine wired remote (both sold separately) features an LCD screen which lets you view source information, so you can mount the KMR-555U marine head unit out of sight. The wired remote allows you to access all major functions of the Kenwood marine receiver, as well as control peripherals like an iPod or satellite radio tuner. This remote attaches to the proprietary 8-pin remote input on the rear-panel of the head unit.
    • Simple Marine Remote: The Kenwood KCA-RC35MR wired marine remote control (113RC35MR, sold separately) is designed to withstand the harsh marine environment. The Kenwood add-on wired remote features source selector, music search, and volume control buttons. This remote attaches to the head unit's blue/yellow wire within the harness.

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input wire (blue/yellow) within the included wiring harness that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

    Was okay before... now its fantastic after firmware update

    Written By Joel_CA, Norcal on Sunday, April 06, 2014

    Crutchfield Customer Review (What's this?)

    This was fairly satisfied with this unit after getting accustomed to its menu and user interface. Browsing through each menu or searching through songs on a playlist was somewhat irritating since the unit was fairly slow and couldn't keep up as you scrolled through a list. After browsing through Kenwood Usa's website, I found out that there was a firmware update available. I quickly downloaded it into my thumb drive and crawled up under the boat cover to update the unit. Let me just say that the user experience has greatly improved. Scrolling through menu's or song lists is much faster with little to no delay. Im so much happier with it and am now looking forward to blasting some tunes in the water once the weather cooperates.

    Good radio

    Crutchfield Customer Review (What's this?)

    I have had the product for a little over a month and it's a great product I like the front and rear USB hook up and it's very easy to go through songs on the radio

    Pros: The display

    Cons: None

    Too soon to tell. Just installed yesterday April 8th, 2013 Looks great and sounds really nice so far

    Product reviews from the Crutchfield Labs

    A marine receiver has to do more than just look good and sound great. It also has to stand up to salt, spray, sunlight, and rough weather. Kenwood designed their 2013 marine receivers and remotes to...

    You will want to contact an Advisor by phone or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff  Jan 06, 2014 ]  Staff
    This will depend slightly on how you are mounting the unit. This is a standard DIN size radio, which means it is basically 7" x 2". For more specifics please reach out to an Advisor by phone or online chat. They can discuss how you plan to install (based on your vehicle) and give you exact dimensions. [ Jeff  Dec 11, 2013 ]  Staff
