What's a good 75x2 RMS amp for a decent component system?
 

6.5" Component system for the front stage at 150 RMS total.

AND

One Kicker Hideaway Compact Powered Sub powered at 150 RMS

That's it! That's all I need. Don't care about a lot of bass or loudness. Just want to upgrade the factory speakers and sound good. May go with the Alpine SPR's for the front. Just curious about any decent amps out there at 75x2 RMS.

I have a 2015 Chevy Colorado. I swear the front door speakers look like 6x8's, but Crutchfield sells 6.5 speakers for my model on their site.

I'm going to order my car audio online and have a professional install it. Would I be able to get 6.5's into a 6x8 speaker fitting? Don't want any crappy 6x8's in the front to be honest.
