i own a 1998 gmc sierra extended cab, my subs are sitting on the back seat behind the drivers seat.

It's a pretty big box (idk cu)
2x 12" pioneer bullets (older subs)
500w rms rockford fosgate amp.

What would be better for this truck, sealed box or ported?
a smaller sealed, or a bigger ported.. i have a big box but it's not ported.

i wanna know how to get the best bass out of these.


thanks a lot

A big (but in spec) ported box tuned <40hz.

i would do 2 shallow mount woofers in a down firing box under the rear seats with a big amp

gimme the money for this.

dumb shit`

Dont ask a stupid question then when you get good feedback get all financially depressed.

Car audio isnt cheap.
