JL AMP Troubles....

So when it comes to boats, I would ground it way differently than vehicles. That looks like it works fine when it's all cleaned up. But for the best performance, I would run all ground wires to the house battery. That alleviates any issues down the line. Also this helps keep ground loop noise out of your system once you start adding more equipment. Best to have one grounding point.

Glad you figured it out. I've got a very strong background in systems and if you ever any questions, just holla. I've been having issues too since I've rebuilt my system but have figured it out and now tuning the darn thing. Anticipating about 30-45 hours just to tune it right hahaha. Going to be long winter! But when I'm done with it, OH WATCH, we might scare some fishies away lol.

The ground bar in the pic is bonded with the negative battery posts. The boat has zincs also.

Ok no worries. If that's the case you need to make sure that all other components like your head unit also grounds to that same point.
