Re: >>>Engine whine and ground loop fixes... take two
I have a slight whine in my front stage, only really noticeable when MY HU is on 0. It makes a "pop" sound when I turn my HU to 0, and when the HU shut's off. Also get a crackle exactly like 2muchbass4u2tak's issue at higher volumes. I grounded my RCA's, but did nothing. My sub has no whine, but I did hook it up to another amp and it had a crackle in it, but went back to original amp and no noise still. I noticed in the OP's picture that he grounded the speaker and sub rca's separate, that shouldn't make a difference if you ground them together should it?
