Marine stereo (Aquatronics) Turns on and then shuts itself off

The Aquatronics MS1550G is a marine stereo, not an antenna. If you are looking to mount an antenna to your boat, you will need to find a suitable location for the antenna mount and then run the coaxial cable to the location where you plan to install your marine radio.
Typically, the coaxial cable will run from the antenna to a hole or grommet in the boat's hull or deck and then be connected to the back of the marine radio. The specific location and process for running the cable will depend on the type of antenna and the layout of your boat.
If you are unsure of the best way to install your antenna, it is recommended that you consult with a professional marine electronics installer or refer to the installation manual for your specific antenna and radio

Aouns like wiring problem with ground wire. Why dont you install dedicated switch for stereo. It is unsafe for electronics to be on while starting motor.

This is a bad power supply. You have to do some serious work at the component level of the unit to fix it.

power supply for the radio taken from a source wire that is affecting the voltage regulation
take it in or have a radio technician come and check the installation

I have an Aquatronics MS1550G radio on my 2006 Suntracker. The radio speakers have sound, but the sound is barely audible. I have used the reset button with no success. Is there a quick fix to this problems?

remove the dask or go under the dash and remove the bracket screws and then unplug the harness.

Hello peter79,

Ive had similar problems with my radio on my sailboat.

This really depends on how you have your radio housed. Is it inside a cabinet, or perhaps sealed in a water tight enclosure ? Is it in the cockpit of the boat or inside the cabin ?

The reason I am asking these questions is because I believe your problem is heat related. If the unit is getting overheated after an hour of use it will shut itself down to cool off. I imagine it starts working fine again after a little while.

The only solution is to make sure it is getting proper ventilation and that you also protect it from the elements. You may even look into buying a Marine Stereo as they will last a lot longer on a boat.

Post back with any answers or anymore info so that I can be of further assistance. Thank you for choosing Fixya!

TAKE IT OUT AND TRY IT ON A 12V BATERRY AND IF IT TURNS ON ITS GOOD AND IF IT DOESNT IS NOT GOOD. IF IT TURNS ON FOLLOW UR CONSTAN AND UR POWER WIRES AND SEE IF IT HAS A FUSE BOX IN THE BOAT/ CHECK THOSE FUSES. AND CHECK UR BOAT BATTERY TOO CAUSE IT COULD HAVE DIED WHEN TESTING THE STEREO TOO IT HAPPENS ALOT ON BOATS

I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.
