Do you have a portable player (ie IPOD) (may need to get the earphone to RCA cable) if your near scarborough I can help you with this) If you do try to hook it up to the amp and see if this eliminates the noise. Make sure to hook it up as close to the amp as possible and do not use the RCA cables from your deck. Try this with the car running, if the noise is gone the problem is either RCA cables or the outputs on the deck. Now did you tighten the chasis grounds and alternator leads under the hood? I know on GMs this is a big problem. You may even want to upgrage the ground from the alternator to the battery and the chassis ground.
