alright, so far i'm gonna be running a clarion 480 to 4 db650's and the 280 to 2 db(maybe mm) 690s on the tower. i'm wanting to build a nice little amp rack that shows the pretty amps, but i can't seem to find a matching sub amp. anyone have any recommendations on wiring up a DVC 4ohm sub to another 480 somehow? i'm looking to get as close to 600watts as possible. i'm thinking that i may have to just hide the sub amp.........
