I have 2 amps, and an electronic crossover, so do I ground them to each other, and then to the chassis, or use a ground wire from each to different ground points? I want to eliminate ground loops without using a filter on the RCA cables, cause that's just it, its a filter...so there is bound to be signal loss, right? I'm going to move the head unit ground from the stock harness (God only knows where it grounds to and with what other stuff) straight to the chassis. My power and signal wires are separate, and the car's electrical has never been hacked on, with a nice new battery and good alt. So...am I missing anything ? That whine in the speakers will make you want to hit a tree, so I'm determined. Thanks in advance.
You will need a ground block.

It allows you to connect the two ground wires and ground them to a single location without any worries.
