Just got my car metered and did 132 DB with two american bass tnt 12's in a 4 cubic feet box tuned to 33Hz on a pioneer gm-d8604. My peak is 49Hz. I see I have a long way to go still. I'm trying to hit the mid 140's but my seats don't fold down. The only option I see is a blow through 4th order. What songs hit hard around 45-50Hz?
