Looking at throwing some subs in my new ride. I've had a F250 with a custom box behind the rear seat, and a dodge ram with a box under the rear seat. Both were sealed boxes, and I was pretty happy with both. But now that I'm in the market for my Titan, I see there are ported boxes, are these really the way to go in a truck? I know my friends Bronco had two 12's in a ported box that pounded HARD. But it was a old school square hatch type box, will I get the same type of effect in a under the seat truck box with 10's? Thoughts, opinions? I'm not looking to spend alot of money on this system, just wanna add a little bass.
