What to push my type R 6x9s and 6 1/2s with?

About to buy a set of ALPINE SPR-69C 6x9 TYPE-Rs and a pair of ALPINE SPR-17C 6.5"s...these are rated at 100 rms / 300 peak..What would be a good amp to push them with? I was looking at the Kicker ZX850.4 4 CH AMP it says it produces 175 Watts x 4 RMS 4 ohms..but the thing is HUGE, 2 feet long ..will this be overkill? I also have a pair of 3 1/2s in my dash, how do I run 6 mids/highs of of a 4 channel amp? Thanks for helping a newb..

you dont need to power the rear speakers. And yes 175 watts for 100 watt speakers is overkill. Thats 75% more power than you need

a decent 4 channel amp, that puts out 50-75rms x 4 @ 4 ohms
