OK I built a really nice console box for the back seat of my crew cab at 4.33CF and tuned it to 40Hz and am running 3, 4" aeros port up right now and sub up at an angle toward the front and I am running 3500 watts (measured with the DMM) to it RMS. I want to know how to make it louder in this vehicle as it seems like it should be louder, I only have a cheap Radio shack DB meter but it only reads 124db??? What the Fu@#! I don't get it, this thing should be bangin for that kind of power and sub?? Any Ideas?? Should I get another 4" port? what do I do?
