ok look here is soem advise if your going to do something do it right or not at all i just installed my subs and amp it was easy as hell. do you have an after market amp? if you do just pull the deck out from the front and then hook up your rca cables. then run them under the center consol and to the back same witht the remote wire. then do your ground from your amp make sure this wire is not more then 6 inchs in length or it will make your amp blow up. its really simple dude don't do a half ass job it will look like shit and won't be the real thing.
