Hi, I'm new to the forum, but not too new to car audio. Setting them up on and off for the past few years. Done a decent amoutn of research. But anyways, heres my issue.
Installed new 4ch amp and everything was working fine cept I was getting alternator noise. Playing around with the RCAs (turn out the rca had a slit in it somehow, hence the interference) however when I plugged the rca's back in my amp was incredibly distorted. Tested power voltage etc and everything turned out ok, new RCAs, doing the same thing. Its been a couple of months and I just have my speakers to the HU (getting a new car this week so haven't bothered doing much testing on the amp). Basically tho, it outputs sound, but gets "crunchy"? , just extremely distorted (not the speakers obviously). All grounds and power cables were ok (shared a ground with another amp and that amp is fine). Any ideas? Think the amp is blown. BTW, ground is about 8" long (as short as I could get it).
