I would have loved to put a mini in my car but it's too late... already got the SFF PC... First of all... Congratz, you got the right speakers. Those Kappas are tops. As far as the amp goes, there is a company called Soundstorm that makes amps with unusually good specs for the price. I was a sceptic untill I got one myself. But if space is a major issue and price isn't, Look around for a 4 channel class D amp. They're fairly new on the market so the price isn't my style. But they've got alot of power with a small footprint and far less heat than your typical class A/B. Alto is making a few... I'm gonna put 2 class B's and a D for a total of 6500watts in my car because I will not have a heat or space issue... In any case... Keep us posted!
