ok so how do u tune it cause i was wanting to do something like that and the boxes would be tuned at 30 hz but i was wondering if the tunnel itself would affect that
i have a 96 tahoe 2 door with 2 15 inch kicker cvxs built to kicker specs with a audiopipe 30001d it does 145 db at 30hz at the headrest but would it be louder with the subs firing up port back toward the hatch
