[kg1961]

I know PGsaid 2.5 to 3 cub but does anyone know what sounds better?
I deep and narrow box or a wide and shallow design? I listen to dance rap r&b
I will be runninig it off my zx500 side of my reactor.
I have 2 8" MB xtr orion mid bass subs under my seats
the car is a E90 bmw 328i
info would be great
the sub can fire up, back, or front...
I do want the sub in the box so you see the name!

Shape doesn't matter, as long as it's not a cube and the sub can fit in it.

Fire it towards the rear of your trunk.
