[QUOTE="mikesw1975, post: 8753452, member: 683468"] I'm confident that the power at the amp is steady 13.3v at rest. I've tested at the point of connection at the amp with multi-meter several times. The 4awg 12v+ (red) cable is connected to the 100a fuse (via distribution block with no other electronics connected); the distribution block is connected directly to boat battery #2 positive terminal. The 4awg neutral (black) cable is daisy-chained from boat battery #1 -> #2 -> audio amp. After running the engine for a while, the voltage reading at the amp goes up to 15v. The Remote cable is coming directly from the P.Control connection from the Kenwood radio head, steady at 12.7v. The 100a fuse looks to be in tact. If it weren't, I don't think I would see 13.3v or 15v at the amp. From what I can tell, the wiring all looks good so I'm stumped as to why (a) I get no LED light-up on the JL Audio amp at all, (b) brand new *cheap* amp LED lights up blue for a brief blip, then goes dark. I'm going to try two things this week: (1) reduce the in-line fuse to 50a which is what JL Audio recommends in the M600/6 user manual; (2) take the JL Audio amp to another power source and see if I can get it to light up.
