I have a 98' dodge dakota that I have been adding components to for many years. I've always had a faint whine in the background, but with a gnd. loop isolator I attenuated it to a tolerable level. I've got some vacation time coming up, so I plan on doing so rewiring to try to eliminate it for good. I have 2 of my amps mounted to metal directly behind the panels in the back grounded to the same metal, and one under the front seat mounted to the seat bolt. I recently read that mounting to metal is not a good idea. Any truth to that? And what about the screws into the metal? Would it be better to mount wood/plastic to the metal, and then mount amp to that?

Yes it is better to not connect the case of the amp to ground by mounting on wood or plastic. You can setup a ground loop inside the amp that will never go away. I recomend you look at the "grond" related posts at the top of this forum, and use the search function for several other discussions about engine whine and ground loops.
Good luck.

Support the12volt.comGood. Maybe that will simplify my project then. I dont seem to get the same noise from my bass amp under the seat
You won't notice the "whine" as much in the subs. It may be there, just not as obvious to the ear as in mids and tweeters. You are on the right track, but take time to read up on running wires before you re-do the install.
