subwoofer is loud but i can't feel it in my car.

Hey are sure you are in phase? The front mid bass driver, the rear speakers and the sub, are they inphase. Yours sounds very much like a phase issue. Provide exact system details.

ive tried to change the phase with very little change. thinking i just dont have the power to move the sub. well i mean the sub box will move to a side of my hatch if i just leave in the middle so i know the sub box is moving due to the vibations.
