Hey guys, I have this month old 13W7 that I bought brand new off of eBay. I built a custom sealed box for it and it is just too **** loud. My moon roof literally cracks open from all of the air this sub moves. It was powered by a 1000/1 - I have pics email me at mymonkeyracing@cox.net or aim thelowestbidder and I will send them too you. I am looking to get around 550 plus shipping for the whole thing. Thanks
