alt noise

So i got in my car today and started driving. when i started the car there was no cd player in it, thus everything was normal.

Once i had the cd in the cd player, i started getting some weird, high pitched noise comming from under the hood that gets higher as i go faster... I'm assuming thats the alternator whining, because it ONLY happens when a source is selected on the CD player (ie, radio, cd,). if turn the radio off (Via remote) the noise will go away, so now im thinking that its a deck-related issue? just yesterday everything was fine. we'll see how evrything goes afterschool when its going to be warmer outside.

but what can i do about this? I've had my stereo in since july and have never had any problems, so why would it come up all the sudden, unless my alt is going out? < if thats the case, and even if its not, bill, what kind of deal do you get from excessive amperage... i'd be looking for a alt in the range of 150 amps.

bad ground or rca's to close to power wire. does it come from the speakers or from under the hood? email excessive tell him your part of the pack nate will get back to you with a price and an amp spec. saturns are hard so i cant gurantee anything. but now that i am an official dealer for them we get an even better deal.

Saturns aren't "hard". I have a 180a in my Saturn. Contact Motor City Reman, I'm sure you will get even a better deal from them.

yea but those are remanufactured alts and we get a discount through excessive amperage because of the club.

all of the alts are brand new. even with your discount MCR might be cheaper.

By remanufactured the only thing reused is the aluminum core.

the noise deffinately seems to come from under the hood but i havn't been able to get down under the hood and figure it out... It just doesn't make sense that it could be RCAs and power wire next to eachother or bad grounds.. i've had this setup for a while now.

yea i see what you mean now could be something unrelated to the stereo all together. check your water pump that can wistle when it goes.

lol.. IU was wondering what he was talking about for sure.

Its probably a mechanical matter under the hood.

A bearing might be going out.

Water Pump
Alternator
Power Steering Pump
AC Condensor Pump
Tensioner Pulley

Start the car up. Get a long screw driver and press on each componet untill the noise is found.
