Looking for something good and dependable, but not overly expensive. Best bang for the buck i guess.

Using it to power a pair of 6 1/2" Infinity Reference 6022si. Also what gauge wire should i run from the amp to the speakers?

Adding a 12" sub later, but i heard i should use a separate amp for that?

I'm doing my system in pieces cause i don't have the time or finances to do it all at once =D
