electronics for pool table room

Just a pool table room? No video? Do you want multi or 2 channel system? How much do you want to spend? What are you running for speakers? Do you listen loud? What do you listen to?

This may help to narrow it down a bit!

no video, just audio, probably 4 speakers and a sub. All music will be played, mostly rock 80%. I do not yet have the right speakers picked out, but have a couple pairs I could use to get by. Maybe even in ceiling.
