Yea it's like a constant bad radio station high pitched noise. I turned the gain down and the speakers got lower with the sound, turned it up and the sound of the speakers got louder but so did the noise. If i turn the sound up it starts to pop loud, i got scared. h:

I rewired the power to the cap back to the amp like in the "after" diagram i drew and i also relocated the ground to another location at the huge screw under the back seat into the frame and still the same thing.

Its not in a ground loop cause i've got both amps and cap at the same ground so it can't be that either. My boy said to double check if the rca's and power wire are touching in the trunk so im gonna go check that now, i've tried everything else. :hs:

 

plus hes saying the sub is fine. the speakers has static...which isnt connected to the cap

 

For the noise, try a ground loop isolator.

$10 at wall mart. Connects to your RCA's.

 

I had the same reaction b00gers did. h:

The cap has a Neg and pos terminal and has to be grounded.

 

Oh, shit. you are right, i have been doing it wrong.

 

I connected the amp that connects to the speakers to the cap also this morning and still does the same. which makes me even more puzzled.

I guess i can try that as plan Q if once i check if the rca and power cable are touching in the trunk.

 

Yup thats exactly how i got it wired but just add another power wire to the cap from the other amp.

 

Does the noise change when you rev your engine or not?

 

This.

 

Thanks but im past the not powering up part.....i got static in the rear speakers that are run by an amp.

yup.
