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.
