Okay so got my system dialed and tidied up. Worked great at the house, as well as in the no wake today, cruised around a bit and it starts blarring bass uncontrolably out of nowhere so I had to disconnect it, even though the homies shore fishin for carp were loving it.

I am not a stereo guy! But I can connect wires and I have a basic understanding of it. Even with remote wire disconnected amp is still lit on power and protect mode..

details about power and ground supply as well as the inputs from the radio.  does it go into protect with the inputs unplugged?

Most of the time it's gonna be your ground.

4 ga. Power wire to my perko switch and 4 ga. ground to neutral on battery. Both ground and power go to a splitter near the two amps, power has two 50a fuses and i have 100a main fuse near the perko.

1.5ft rca cables from head unit to battery.

Noticed another funny thing, when I turned the blower on at the launch ramp, my radio turned off for a few seconds... I need to clean up the power source for the head unit by tapping into my big power wire from battery switch.. And I don't know if I trust the Chinese rca cables that I bought in a pinch. The every wire hookup is tight and I tightened the wingnut on neutral post on battery with a crescent wrench. The amp for the speakers doesn't miss a beat, the amp for the subs that is having problems is a 250w JL

Haven't tried disconnecting rcas to see if its still on protect, I pulled its fuse yesterday immediately so it wouldn't damage my subs. I've had the amp in the boat for 9 months, I don't think I have ever seen the protect light on.

 Your amp is allergic to water.  Put it back in your car.   >:D


 OK, being serious.  Is there any chance the amp got wet while you where on the water (wet towel, life vest , ect) ?  Could also have been damp inside from condensation if the boat is stored outside. Check the back of the amp for signs of water,  you would not believe how many times I've removed seemingly dry amps and found water under them.  If the carpet under the amp is wet, use some 1' long spacers between the amp and its mounting surface.  This will allow moisture to escape and not get trapped under there trickling into the amp.  It will also help the amp run a bit cooler.  ;)

 Also could have been a voltage issue.  Some amps will do strange things with low voltage.  Even different models of the same brand will react differently.   The clue about the deck turning off when you turned on the blower is an indication of a voltage issue.  It might not be just with the deck.  What was your voltage gauge showing when you had the problems ?  Are you 100% sure the alt is charging and both batteries are good (I assume 2 because you mentioned a perko switch) ?

Batteries are die hards bought in October, yes the alternator charges and there's no drop in voltage at high rpms.

The boat is outside but its in a hillbilly circus tent that doesn't leak nor let anything condensate. Amp and carpet were bone dry on the lake. I was only on the water 2 hours. Stereo ran for 12 hours yesterday with no problems and the air was more moist yesterday than its been. The radio shuts off when I hit the blower cause it needs its own wire ring terminal'd to the perko and its own ground wire instead of the super thin factory wire. Or I can tap into the 4ga cables I have for power and ground. I didn't figure I'd have power issue with h/u since the amps are pushing speakers.
