I'm looking to install some in-wall speakers in my kitchen and an amp to drive them from a Squeezebox. I'm thinking of going with 6X9 3-way car audio speakers -- primarily because of price, although I'm considering "real" in-wall speakers also.

Can anyone suggest a good amp to go with this type of setup? Ideally, the amp could be installed somewhere inaccesible and permanently wired, or would be small enough that it would be invisible if mounted on the bottom of a kitchen cabinet. Also, a low price would be really good.

Thanks for suggestions (on the amp or any other aspects of the proposed setup).
