Is it under warranty? I'm not trying to screw over the people in here, but if it's under warranty and you got it from an authorized dealer, you could get another free one and sell that for a lot more $$$.
Or you could find out how much it costs to get fixed, then possibly still make more than what you'd get from a broken sub.
He had this sub for 5 days now going on 6 and I wander if JL Audio makes enff money off people like this... DONT PUSH SUBS TO THE MAX AFTER U GET THEM INSTALLED. MAKE SURE YOUR OHM LOAD WORKS FOR YOUR AMP AND SUB. AND IF YOUR JOKING PLEASE DONT TYPE IN ALL CAPS, IT GETTS ANYYOING TO READ AFTER 3 TO 5 SENTANCES. IF a joke dont waste are time with it
