i say not on full power cause im breaking them in i have my volume on the headunit set to 28 and bass knob about 3/4 of the way up when it starts to clip, im scared to turn it up on low songs right now cause the papers i got with audioque subs states 10-12 hours of playing time at moderate power with low excursion, avoid playing low frequencies 20-30 Hz at high power levels for the first 10-12 hours of playing time. This is necessary for the multi-layer spider system incorporated in the suspension package to achieve proper final "set". Failure to properly break-in the subwoofer could result in excessive suspension noise.......exact quote from paper i got, now i wouldn't want that now would I?, i been getting down on the knob pretty good, and have seen the light a little, but during the term lab, i have tried a hair trick and it did a decent one, but i wanna let em break in more and get this knob fixed, probably just buy a new one, and like i said ima move the batterys around to get more space between box and back window and hatch, this thing is suffocating! Need air!, so trust me when i say not on full power and such, and then i'll post up a hair trick, might not be absolutely awesome, but to me its something, and im proud of it damn it! and i typed all this with a smile on my face, its all good fellas!
