Cheap subs

[Racing Rice]

Okay, Im looking some some cheap hardhitting subs. When I say cheap Im talking less the 250 for a pair or maybe even one. Heres my I have a amp thats good for about 400x1@2ohms (USAcoustics).

I already have boxes for 12s one of my old infinity references are starting echoing. The other is okay. Im a cheap ass, so I want to try to stay in a lower price range and get some subs that hit fairly hard at the same time. Im not going for competition or anything. I just want something that I can feel.

Any suggestions? I was thinking maybe some Crunch Fatboys or something along those lines.
