in my opinion, the bang for buck on this sub is rediculous, i was looking for 2 12's but found this to be a perfect match to my amp so i gave it a try and i definatly dont regret it at all, it POUNDS, lol shook my coworkers work van at a stoplight to the point he mentioned it in the lunchroom the next day :) i have it in a sealed box, (slightly quieter, but less mushy loudness) and i woudnt go for 2 12's anymore ever again, great sub,
I've got 1 of these subs in the back of my car. got another one on the way. one hits hard , so two will be insane. got a 1500 watt clarion mono amp, 0 gauge wiring, two batteries, it gets the job done.
i bought one of these and it had a slight clattering sound to it. i took it easy for the first two weeks to break it in. after about a month and a half it progressed to a horrible clatter. sent it back to Online Car Stereo to be fixed or replaced on warranty. it has been over two months and i haven't received anything back. have done business with them before and had good service. But this is enough to make me take my business else where. I email and get no response. Called customer service and they said they had no clue on how long it would take.... big thumbs down!!!
