Trevor what sub/s are you running. Did you find that the DSpeaker improved midbass punch at all. I have a pair of 12's in my midsize car and a ton of power and they punch you but good . The 2 10's in my theater just dont have the midbass punch. I see many people on AVS building midbass modules to get that punch in the chest from the 100hz range. In my previous car i had a hatch and i faced a 10 towards the back of the car and that thing absolutely pounded, nice back massage smile The bigger the room the more sub you need.

DOG is GOD spelled backwards.
What others think of me is none of my business.
