this is mainly for Colorado MJ NewB. I saw you were making a pretty cool system for your manche. I figured i would tell you what i am putting in my g/f's cavaleer or w/e lol. i origanaly was goign to use 12" pioneer impp subs and prolly a pioneer 1500w 2 way amp. but i remembered about the brand volfenheig ^_^ So. I decided to use them instead. i bought two 12" 1000w peak subs and a 2000w 2 way amp. (which was actualy supposed to be a 1600w they sent me the wrong one ^_^) and a 2 way crossover. all volfenheg. We got the receiver from bestbuy (ewww) for $200 including the antena adaptor, installation kit, and wiring harness. I am in the procces of fabbing a fiberglass box that sits across the bottom side of the back of her trunk with the subs facing up and crossing each other for a good carry through. fiberglass will be painted red, not felted... Ill try to takes pics of the procces. ^_^
