JL Audio 13w7

13.5" JL Audio w7 subwoofer in a spec built 2.375 cubic ported enclosure, powered by a JL 1000/1v2. Q-bandwidth-0.8, center frequency-45hz, bass boost-+4, 12db slope, subsonic-25hz. Infinity Kappa 3 ways powered by an Alpine PDX-4.100. Monster 0awg powerflex wire split to Rockford 4awg to each amp and the RF 1 farad capacitor. Rockford embroidered RCAs, big 3 upgrade, 70 square feet of Dynamat covering all four doors, trunk, and firewall with Dynapad on floorboards. Extremely punchy and tight even when ported. Damn I love JL...
