I have interference in my speakers but can only hear it when the cars off. Ever since the amp went in.

Personally, I would take the trim off and move the loc and see if that has a effect on the feedback.

Failing that, insulate the wires more.

Failing that, get RCA's soldered to your IQ.

Strange, is it high pitched?

 

[chappo1994]

Thanks for the help
And yer it's high pitched only when the car is turned on when the alternator is charging because as u rev the engine the pitch gets higher and louder it's fine when it's above like 20 bumpin along but it's unbearable below that im thinking it's my loc cause it's also connected to my battery because it has a relay that activates when the speaker turns on giving remote out

Have you earthed everything well?

VE is notorious for alternator whine. Some cheaper places like JB Hifi etc will actually refuse to warranty against it because in some VE's its almost impossible to get rid of.
