SUPERB QUALITY

I have 3 level 3 M3 12s duel 2ohm wired at 1.33ohm on 5k watts amplifier. They have all the upgrades except the direct leads option. With upgrades I paid $460.00/per subwoofer from DCSOUNDLAB.COM. I definitely recommend ANY DC AUDIO PRODUCT to anyone wanting quality sound and supherb build quality. Also... These subs perform best in a 4th order enclosure.
