I am installing a 12" rockford sub with a mtx 280 amp. I hooked everything up and it worked great in my driveway and everything was fine. I took the boat to the lake and when I turned the key to start the boat everything just shut off. When I turned the key then nothing would happen. I unhooked the amp and put the boat back in the water and it started and worked fine. I have since tried hooking the amp back up and when I do the boat will not crank and the guages flutter and the ignition beeps repeatedly but nothing will happen. Now when I have the amp hooked up the power light on the amp will not come on but a voltmeter showed that 12 amps were getting to the amp. The boat still will not crank with the amp hooked up. Any help would be appreciated I am getting very frusterated.
I have the 2 RCAs going from the deck to the amp. The remote wire going from the deck to the amp. And the power and ground are directly to the positive and negative on the battery. Is there something wrong with that?
Do not ground to the engine block...ground back to your battery. Something may have come loose on your drive to the lake. If you say you wired everythign acccordign to the diagram...then your amp is broken. My guiess is you wired something wrong. look back at the diagram. If wired correctly your amp should have nothign to do with yrou guages.
The power wire is 4 gage and the ground wire is 6 gage. I hooked up with amp to a battery separate from the boat while still being hooked up to the remote wire from the deck and it will not turn on. Im guessing the amp is toast. I have no problem getting a new amp I just dont want this to happen to a new amp if I buy one. The amp I was using was probably about 9 years old but obviously did work when I first had it hooked up in the driveway. I just dont see how it could be wired wrong when it isnt a very complicated wiring scheme.
