GregoryAltieri Posted September 18, 2011 Report Share Posted September 18, 2011 got 2 dc audio level 4 12's in a 1999 vw passat trunk wall off a powerbass 3k and for some reason I dont get the lows well at all, however anything in the 40hz range I smash the hell out of, and I used the torres box calculator for my tuning but it still doesnt seem right and ideas?

OrionStang Posted September 18, 2011 Report Share Posted September 18, 2011 Double check the subsonic filter on your amp. Box looks ok Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
GregoryAltieri Posted September 18, 2011 Author Report Share Posted September 18, 2011 subsonic is all the way down, and the lpf is around 80 or so, is it due to a trunk wall? Quote Link to comment Share on other sites More sharing options...
Winn Posted September 18, 2011 Report Share Posted September 18, 2011 Just because the tuning of the box is what it is. doesnt mean the resonant freq. will be low. its only in the equation Quote You know how you avoid that?

n8ball2013 Posted September 19, 2011 Report Share Posted September 19, 2011 yeah but if i see a box facing forward without it being sealed properly ill be seeing the reason why its sounding like ass down low.
