When i put my a/c on i get alternator whine.. im pretty sure thats wat it is cuz i used to get the same exact noise with my system until i cleaned up the wiring... any ideas please.. its really annoying and summer is right around the corner!!!

 

tighten the belt....or change the belt...or change the alternator

 

are those the only things that could be causing it??

 

are you saying that you are getting a stereo buzzing/whine while the ac is on? or is it a noise coming from under the hood?

 

yes, im getting a stereo/buzzing whine that seems to come from the speakers... I used to have this b4 because my wiring for my audio system was messy... i cleaned it up and the noise went away.. now i get it when my a/c is on... def not from under the hood... only happens with the a/c

 

did you ground your stereo/amp to the same spot as your ac?

 

they probably arent grounded in the same spot. i would check the ground for the ac (you will have to look up where that ground can be found @). and i would check the ground for your stereo (check amp ground and deck ground) if your deck is grounded through the harness, you might try and relocate it, be it directly to the battery or whatever. also i would try and move the ground for the amp.

 

thanks... so basically i gotta check the ground on my amps, a/c, and head... anybody have any idea where the ground for the a/c is cuz my repair manual wont cover a/c... says u have to be qualified... ppsshhh
