I also added a house battery for my amps and tied it to my center engine with an automatic charging relay that has starting isolation. Works like a charm. When the engine is running, it combines and charges both batteries.. if either battery voltage drops below 12.75 volts, it disconnects them and when I start the engine, it automatically, disconnects them as well...

sorry for the hijack, but this info could be helpful to OP..

Nice job on the wiring,very clean! Where did you get the distribution blocks with built in fuses?

Thanks. I'm a bit of nut when it comes to this stuff. It was a lot of wires so I wanted to keep it neat so I mounted everything on a piece of 1/4" starboard.

The distribution block is a JL Audio (XD-FDBU-4) 4-Way Fused Power Distribution Block. I believe I ordered it and the 50A fuses for it from their website.

Can you run off of the remote and ground from the 1st amp?

A cap is not designed for reserve time, and won't have a purpose in a boat. It stores energy for when current draw is needed - like when bass hits. That's only applicable in a car/truck, and it's to help take a little load off of the alternator. In a car, it's a band-aid at best.

I ran my second amp and I used the power distribution block for my power and ground. Now I am getting interference from my new amp when I run the blower. Do you guys think this is a grounding issue? It's weird that the ground is ran from the distribution block to both amps and only one is giving me feedback.

Any ideas?

Thanks!

Dirty power is fairly common in mobile systems. Could be a ground loop issue. How are amps grounded and the blower?
