[rivan513]

I'm trying to get a box that actually Sounds good with a lot of bass. (rap music) I've tried 5 different prefab boxes with no luck. I'm running 2 RF P3s 15s duel 4s with a MTX 7801 @ 1 ohm. Have upgraded electrical and 2 batteries.. ported/sealed I don't Really care.

Truck is a 04 suburban so lots of room to work with. Plz Any help would be appreciated. Ty
