Just wanted to say for my first setup I had a cheap 15" Audiopipe TSVR-15. Its 74 bucks on ebay, 500watts RMS. I ran it with the Audiopipe mini amp which is 600w @ 2 ohms. thats the APSM-1300. Since the sub is 74 bucks and the amp is 110, its pretty good for the price in my opinion. Ive moved on now and upgraded, but for my first system I was happy with it at the time. Also had it in a crappy sealed box. Or you can get 2 12" TSVR-12s and wire them down to 1 ohm for 1k off of the amp. Just a suggestion
