I bought mine in pieces but I got my pwr wire from praxair a welding supplier in town, got 20 feet of number 4 (4 awg) for 16$ only thing is the cables are black but i don't see em and it looks nicer in the engine bay, some guy at a stereo shop told me they don't flow current like regular car audio power wire but he was just a sales man.. dunno what he knows, but I have no problems running my 2 eclipse 33230s off this cable with the gains cranked all the way.
anyway point being get the cheapest but best for the application
