[QUOTE="bbeljefe, post: 8212015, member: 655960"] You need to check all of the ground connections and all of the positive connections on your amplifier and on the capacitor. You could also have stressed a signal wire and that could be your noise problem, although I'm betting that the problem is with a ground connection. You should also replace the ground wires with wires of the same size as the positives, which in the case of that Scosche kit, they're 5 gauge. You don't need to throw the capacitor away and you don't need to upgrade to 1/0 wire and 1/0 big three unless you're planning to upgrade the power you're running, as the wire you have is sufficient for the current your amp needs. A big three upgrade would be wise but to be sure, 4 gauge is large enough. As for the capacitor, it can help a system like yours and it does not present an electrical problem for the alternator. As you've mentioned, the cap stopped your dimming and if that's what you bought it for, then it's doing its job. Also, it would be a good idea for you to share the make and model of your head unit so we can determine whether or not your gain is set too high. Judging from the other equipment you've listed, I would hazard a guess that your head unit doesn't send a very strong signal and if that's the case then your gain probably isn't set too high. But again, it doesn't hurt to confirm. In the end, you had no problem until a wire got stressed, so let's first worry about resolving that problem before we design and build an entirely new audio system for you. ;-) [/QUOTE]
