Giuseqpe Posted August 1, 2013 Report Share Posted August 1, 2013 I have a aq hdc318 I'm about to build a box for. I've never really built a box and I don't know how to calculate port area and such. I'm going to run it on a dd m3b. Its going in the back of a passat estate, I have like 20x40x20inches to work with. Maybe a little more of needed.

Giuseqpe Posted August 2, 2013 Author Report Share Posted August 2, 2013 My car is a passat estate, I have a 120amp alternator, really not planing on upgrading it.. it'll cost me like 1000$ in Norway.. Big three is done. Batteries I haven't bought yet, but im thinking 2 of the bigger xspower or 1 small and 2 big stinger ones. Amps are dd m3b and a rf t400. All 0 gauge cable.
