Visonik V212BS Car Audio 1500 Watt Dual 12" Sub Enclosure Amp Combo
First of all I must say, amazing rich sound for it's price. Second of all, with a bit of tweaking it can kick crazy hard and still hold its sound. It also fit perfect in the back of my car (96' Ford Probe GT) which is an added bonus.  The only thing thats a drawback is on a few songs the bass hits so hard on itself the make a slight rattling sound. All in all I'm love this product and love my decision on purchasing it as well.
