Audio setup 997tt cab
 

Hello, all, i am wondering if this system set up make sense and hope to improve sound quality.
i have 997 tt cab with bose system but planning to get complete system.

1)HU pioneer avh 2330
2)focal 2 way 6.5inch component system(k series) in front door(or should I go with 8 inch 2 way system from focal?)
3)focal 4 inch(focal pc100 or isc100) in rear
4)shallow mount 8inch sub x1 in stock woofer box(modified to fit).

I am wondering if i can get 3 channel amp to run front speakers and 8inch sub and rear speakers powered by HU?

let me know what you guys think.
thanks for the input.
