Thinking about competing, need help!

Well, since I most likely won't be selling my car and won't be having a speed demon (haha), I am thinking of going into audio competitions. I hooked up with some really nice buds from work who know their shit about sound and could get me hook ups and all and hlep me install.

This is what I currently have.

A Kenwood Deck
KDC-MP8017 CD/MP3 Receiver

Receiver to be exact.

Now I want to add some subs, so I'm thinking about 2 x 12" Alpine Type R's. Got lots of props for those subs.

Now what amp should I run with those to power them enough.

Also what kinda db levels do you think I'd be hitting with those in my car? I'm actually hoping to win something, or maybe come close to. Any advice would help.
