My girlfriend just bought me a 4 channel amp for my birthday. I hooked everything up and now I'm hearing alt whine out of my tweeters, but not my coaxials.
Also when the volume is at 0 my subs move and when the song changes there are short little bursts on the subs. Someone told me it might be my ground so i redid everything and as far as i know my ground is good. Would a ground loop isolator do anything?
