i just installed an old eq two amps one for my highs and one for my sub. the problem is i am gettin alot of engine noise. i seperated all the wires but still get noise. would the gauge of my power wire make this happen.
If you disconnect the RCA inpus to the amp(s) are you still getting the noise? If not, the RCA's are to blame. You should re-route them making sure to keep them away from any power/ground wires and the computer. If the nopise does not go away, than a faulty ground is likely the culprit. I would reground it making sure to use a solid connection to the body and scraping all the paint away from the area where your ring terminal touches the body.
