A seaworthy Sony

Sony's DSX-M55BT digital media receiver is made for marine use, so you can enjoy all your favourite tunes when you're out on your boat. Built-in Bluetooth® and a handy front USB input give you plenty of ways to play your digital music, while the coated circuit board, UV-resistant front panel, and anti-glare display ensure reliable performance for seasons to come.

Bluetooth® convenience and more

The integrated Bluetooth offers Simple Secure Pairing, so you'll be streaming music and taking calls on the built-in microphone in no time. You can also plug your iPod®, iPhone®, Android™ smartphone, or other device into the front USB port and play MP3 or WMA files while charging the device. The display shows song title and artist info, then gives you caller ID when you get a call.

SiriusXM satellite radio

You can also add a SiriusXM satellite radio tuner (not included, requires subscription). Satellite radio offers an unparalleled variety of music, news, sports, and talk, and your favourite channels will stay with you, even when you're miles offshore. No wonder it's a feature more and more boaters are looking for.

Get the sound you want

The DSX-M55BT features a built-in Dynamic Reality Amp that's designed to produce plenty of power without noise or distortion. You can also customize the sound to suit your musical tastes using the built-in 5-band equalizer. If you like bass-heavy music, Sony's Mega Bass really brings the beat. And the 2-volt rear-channel and subwoofer RCA preouts will come in handy when you expand your system in the future.

Installation note: This marine radio is weather-resistant, not water-proof. We recommend mounting it in a water-resistant enclosure or using a receiver cover for best performance.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

Marine, Display, & Remote Features
Marine Rated: The Sony DSX-M55BT marine-rated digital media receiver is ready for the marine environment with a UV resistant coating and coated circuit board. The Sony marine receiver is specifically designed to withstand the ASTM G154 test for UV resistance.

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. If you turn the ignition switch to the Off position without detaching the front-panel, the caution alarm will sound for a few seconds. The alarm will only sound if the built-in amplifier is used.

High-Contrast LCD: The head unit's LCD screen has 5x higher contrast than conventional screens, and the optimized viewing angle makes reading easy for drivers. The LCD screen displays source information, clock, station ID, and track data when playing back digital files from your external USB devices.

  • Auto Scroll: The Auto Scroll feature allows long displayed items to scroll automatically across the display when the track is changed on a USB device.
  • Dimmer: The DSX-M55BT feature a dimmer mode to dim the brightness of the display. You can choose from either Dimmer On or Dimmer Off.

Pressing and holding the Source/Off button for one second will turn off audio output, but the clock display and button illumination remain on. To turn the unit off completely, you must press and hold the Source/Off button for two seconds.

Auto Off: When installing in a vehicle without an accessory power wire at the radio location, you can set the unit to turn off all lighting a set amount of time after you turn the power off. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

You can control basic playback functions like Play/Pause & Previous/Next Track from the head unit's front-panel. However, advanced music browsing will still need to be done from your Bluetooth mobile device. The head unit will also display your stored music and music app's song information; such as Artist name and Song/Album title (not compatible with all apps).

kenneth  Jul 28, 2021

It does not; just an ASTM G154 rating for UV resistance. If it will be installed where it could get wet, then a marine cover should be installed with it:

There are a couple ways that this receiver supports a subwoofer. I recommend contacting an advisor by calling 1-800-324-9695 to discuss the method you want to use and to get a personal recommendation on the current subwoofer that best matches the plans and installation location.

Can't say for sure. I installed radio in a Yamaha UTV. I'm thinking I adapted harness to existing plug with in-line splices.One of those obstacles one fixes and forgets.

How do you wire this to a 3 amp system? One amp is for the sub woofer, one amp is for the boat speakers and one amp for the tower speakers.
tim  Aug 01, 2020
1 answer
You can only send 2 distinct outputs to Amps in addition to the direct powered speaker set you choose. Run boat speakers off direct and towers/sub off the amps. Most waterproof speakers will sound great with 55w from the unit unless you're in blast mode. Not my thing but to each his own.

I have an 07 Harley ultra classic and I can barely hear my stock radio and speakers over the exhaust. I'm thinking about upgrading to this head unit with the sony 100w 6.5 speakers. Would this unit help me with sound volume?

Yes i have this radio and it is super loud. The only issue is that it's not that easy to operate.

Yes it should. I have that radio and it is super loud
nathaniel  Jul 08, 2020
I think this would help a little but have my doubts on making a big change. I recommend contacting an advisor on 1-800-324-9695 to discuss all your goals for the sound and get a recommendation on a setup that you can easily hear over the exhaust

Depends on what you are installing the new unit in.. Is it a direct replacement? Is it the same size unit? You may need an installation kit or a wiring adapter kit. Check with your Crutchfield sales rep for install tips.. hope this helps.

I replaced an original Clarion in a 1999 Malibu ski boat with this Sony. The box included everything I needed for that upgrade, so I believe it will have everything needed for your application.

Can I control the stereo volume from my phone? the head unit on my boat is on the other side from me. I don't want to just control the bluetooth output volume because that reduces the sound quality.
borchert  May 15, 2020
2 answers
You will need to control the volume either through your phone/connected device which would be Bluetooth or with the remote that comes with this unit. If using the supplied remote you will need line of site to your head unit. My head unit is in a small bathroom on my deck boat opposite side from the driver but find if I have the door open it works fine. Based on your question this may be your best option.
marc  May 15, 2020
I am unaware of a method to control volume on the unit using a phone other than co trolling the phone's output volume.

zibby  Jun 09, 2018

They do not list the "RC-1B" as a compatible remote but it may work. The stereo itself comes packaged with a wireless remote (RM-X231) so, you'll have a compatible remote regardless.

Is it possible to properly and safely power and use a marine head unit from an 120v AC outlet (with appropriate 12v DC converter) for an outdoor patio application in a stereo (2-channel) format? Would both left and right channels be bridgeable to power a more watt-hungry speaker?
kyle butler  Apr 06, 2018
1 answer
It's *possible* to use a 12v/marine head unit at home with the appropriate converters. However the Sony DSX-M55BT's amp is only pushing 17 watts RMS x 4 channels at 4 ohms (non-bridgeable) which wouldn't be an ideal amount of power for most home stereo applications. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat.
david  Apr 16, 2018 (Staff)
The DSX-M55BT manual states that an internal amplifier rear channel can be used for a subwoofer, but doesn't show how to wire it correctly. Is there a correct way to do so? I have a special application that can't use a separate subwoofer amplifier.

I had the same question unfortunately, I did not have any answer to this question when I bought this receiver.The Sony DSX-M55BT will work with the RM-XM10 but there will be no display on the remote. The DSX-M55BT has no Unlink din data input only remote minijack input, antenna, & sat connector. This remote requires both Unlink din and minijack connections to operate. If this is an issue upgrade to the RM-X11.
