I am currently completing a new box for my wagon, 4.5 cubic foot, 2x100mm diameter ports that are 240mm long, with 4 MTX T4104 (10inch) subs, run by a Rockford Fosgate 800a2, putting out ~960wrms at 2ohms. It is level with the window line. I have the standard alternator, but am using a truck battery.
Will have the car up for the Vic. Drive In night this coming Friday.
