Cheap home audio Amps

ok, this summer some friends and I are doing a little "creative thinking" Last summer we made a kick ass poker table, this summer we are going to make a kick ass beer pong table (if you don't know what it is ... it's a college drinking game)

One of us had the idea to use my old infinity perfect kappa as a free air sub and have it showing through the middle of the table through some plexi.

now my question is where can i find a cheap, and reliable amp. All it has to do is accept RCAs for signal and put out 100 watts RMS at 4ohms.

Thanks a lot for your help.

Try to find just an old 2 channel amp on eBay. You should be able to find somthing for you application.
