amp suggestions
 

I need help in getting an amp for my speakers, what I have are a set of cdt cl65 components for the fronts (150rms @ 4 ohms) and infinity kappa 62.9i in the rears (75rms @ 2 ohms), the problem is that the fronts are 4 ohms and the infinitys are only 2 ohm, so any suggestions for an amp (prefer to run everything off one amp) and also what gauge wire should I run for the speakers?

Just about any 4ch will do for you, that said I'd suggest looking for something 75x4 or more.
Just gain the infinity's down a bit to compensate for the extra power they'll be seeing.
As for wire gauge, 16-14 will be fine for most applications.
