is this a 4 channel amp???
You always want to run your Power wire on the opposite side from your RCAs... you have your power wire on the left side of the truck and have your RCAs on the right side of your truck and amp in the middle.. Check your ground if you have time and make sure that theres "metal" under it. scratch off some paint to get a good ground and tighten down good..

is it a whine or a rumble? cuz alternator noise it a whine. the rumble would be more from an amp clipping..
