My cd player is in a boat, when you turn the volume up to about 28 the unit shuts off and then turns back on. It plays fine when the volume is below 28. Is there some kind of protection on the unit that I could shut off??? And how would I do that???

Re: CD Player shuts off
Since it is in a boat you may have some slight water damage.You should take it in to be cleaned very soon. The longer you wait the worse it will get if this is the problem.
if you are planning on fixing it yourself you wil need to take it apart completley (be careful and don't force anything out) and look it over for any little bit of corrosion on both sides of the main board.
If you do not have the proper chemicals to clean it, you can use isoproyl alcohol and an old toothbrush to clean any corrosion on the board.You may also need some solder joints reflowed as well.
They do have a protection circuit, but there is no way to disable it easy. You would need to lift the proper pin (87 & 89 on IC1) on the microprocessor, but that is not a good idea ever. They go into protect to minimize any damage that could be caused. It would also be a fire hazard if it does not shut down when these things are detected.
If this is not the problem, you may need the amp IC replaced or you may have a speaker that is starting to go bad.

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
Have you checked all of the connections on the speakers, stereo, etc. Being a marine CD player, the wires and connectors are exposed to more elements than a car CD unit. Check for corrosion and make sure that all the speakers are hooked up to the correct "+" and "-" terminals. Not sure if this will help, but thought I'd try. It does sound like a speaker connection problem.
Disconnect speakers one by one and reset the unit each time. If the speaker is blown, or the wires are frayed, it will shut down the internal amp. Also check the fuse in the back of the radio first, it should be near the wire harness. Power cycle the unit as well, unplug it from the power source, plug it back in. Hope this helps.
I don't know if you have figured out how to turn the AUX port on yet, but I just figured it out. First, turn the CD Player off by quickly pushing the "Source" button. This is also the volume knob. Then, after the player is off, hold down the "Source" button. This will bring up the initial setup. Use the arrow keys to navigate through the options. One of the options is to turn the AUX port on. Once this is finished, turn the unit back on and you're ready to go.
