Please help me with an amp!!

I was painting a house and a guy gave me a 10" sub in an enclosed box. It is a Pioneer TS-W254C.

The back of the speaker says
-4ohms
-500W MAX
-250W NOM
Frequency responsiveness 18HZ - 2.5 kHz
sensitivity 87 dB

Since it was free I would like to put it in my firebird but I have no idea what kind of amp I need. I would really like to get a pretty cheap amp. I am not looking to impress other drivers. I just want to have some decent bass when I listen to rap or reggae. Thanx

find a 2ch amp that does around 2-300x1 when bridged

Check out JBL and Profile California for some good budget amps (among others that everyone else will list)
