I dropped the amps down a bit and got the ol' single sub up to 153.9 dB

On paper "1/4 ohm" but I measured 0.6 DCR total on my DMM so 0.3 each amp DCR.

154.1 @ a dB Drag show in Andrews, SC on Saturday... although, I think my 154.0 score from the second round of "head to head" will be the one that sticks on my stats page.

Adding dampening to hatch did nothing at all... screwing a board to it lost 0.4 dB.

I currently have a box with four 12s which seems to have the best potential so far.

With two 1500s and four of my entry level SA-12s it has done 153 dB... with two 3500s turned WAY down so the subs will take it, 154.7 dB (posted another thread on this).

If I had Nightshades and more power it would be dangerous - will get that in eventually.
