Alternator whine. Possibly caused by a ground loop.

You could try a ground loop isolator and see if that helps.

Are you running an amp on your speakers, or just the deck?

 

check ur grounds and also u can use as stated b4 ground loop isolator .

 

is the noise coming from the speakers?

if so you might be getting electrical noise.


my car has alternator wine even without my stereo system installed, but when i ran my RCA too close to my power wire it made noise through my speakers

what is a ground loop isolator?

 

bizzump

 

hmm, i might just get a ground loop.. i think i need 3, since i have 3 outputs.. sub/f/r speakers

 

are the power wire and rca ran on the same side of the car? if so split them apart.

 

ill see

 

sounds like a ground loop

Eh, even if the RCA and power wires are on different side, noise will probably still be there. The car chassis is a great source/conductor of noise. The RCA will pick up noise regardless of where they are positioned. Best thing to do is minimize the noise pick-up with twisted RCA cables.

 

thanks for the info guys, but i think imma figure this on my own. and yes its a ground loop problem. im going to rewire my whole audio system.
