Hey guys..

Anyone have any problems with Engine whine after putting in an aftermarket stereo? I have a panasonic deck right now that works ok but today went a bought a $1500 pioneer deck and after we put in the noise was crazy!!! I know its t the deck cause we changed 3

 

sorry guys my confuzer stopped..

Its not the deck i tried 3 decks and even my buddy's out of his car and we got the same noise?? So i was wondering if the 2003 p5 had and grounding problems? Cause thats what it sounded like to me?

Anyhelp would be great!!!

I would invest in one of those little boxes from walmart that is supposed to surpress engine noise. Not sure of the technical term but i'd be willing to bet 99% of your problem is in your wiring.

I've had 3 different stereos in my p5 and not one has engine interference noise.

 

Thanks for the reply.. But i know the instal of all the other componets are good pro instal.. I have 2 10" subs 2 amps MB Quart seps in the front and rear. I have tried a noise filter allready but still no help... So im just grasping at straws right now....

 

hmm how are the rcas installed?

 

the rca's are ran dow the passenger side of the car and the power and remote turn on are ran down the driverside.. and the rca's are taped after being pluged in.. I was kinda wondering if it might have somthing to do with my alt???? My rpms have been droping latley when i come up to a light or a stop sign??? it will drop to almost 200rpm then come up. drop agian and then be fine, until the next light??? i have no idea what is causing it??? I was told by a couple shops in town that mazda and for cars are notorious for having bad chassis grounds? not sure if that is true or not.. Where do you guys have your amps grounded to???? Mine is the seat bolt!!! Any help would be great!!!!!

i have mine grounded to a trunk bolt. i say run a ground from the strut or something to test it out and see if it gives any dif results. i know i had whining noises when i had a bad ground and my rcas where run close to the fuel pump.
