Sounds like you just wanna build something like your buddy. I'd take some suggestions from these guys and blow his sh^t off the block. IA or Sundown for sure, good choices guys.
IA and SD are not the best brands. Any Zenon board will be good. IIRC, they're built in Korea, rather than China, so their build quality is a bit better. I'm not sure what kind of board IA or AQ uses, but I know SD uses Zenon. I forget who else uses Zenon... I believe RD does. Bah, I don't remember.

That hurted my brained.
Anyway... a lot of people prefer some brands over others for build quality, as well as quality of internal parts.
Just because an amp says it can do X Watts-RMS at X-impedance (Ohm), doesn't meant it really will... and if it will, it doesn't state how long it can do that, or when the amp will die.
We suggest amps based on life-span, true power ratings, efficiency, and quality.
A lot of people will just say " IS BETTER THAN !" with no real knowledge of the product, and most of the time are just wrong about their assumptions.
However, IA, AQ, RD, SD, JL, JBL, Stetsom (As of late), and there are a few other companies that you can find floating around these kind of forums.
