Looking to upgrade my system, not sure what I want to keep or sell so trying to see if anybody wants any of these. '05 L5 12" dual 4, I made a ported box for it tuned around 34hz almost 3 cu. Next is a hifonics amp powering it, 600 rms @ 1 ohm, 300 @ 2ohms. great starter sub, never gave me any trouble, nor did the amp. I take frequent 3 hour trips to and from home, and this amp has never went into protect during any of the 3 hr long drives. If there's serious interest/buyers I'll get to taking some pics, thanks.
