ld school stuff

I wanna design a system for this car as it has no audio in it, I don't wanna go crazy and would like to use the stuff I have.

fronts
mb quart
6.5 inch driver
4 inch driver
tweeter

fronts I was gonna do 6 and tweet in a kick panel and a pair of 4 inch in the center of the dash to replace the factory 4x10

Rear 6.5 2way mb quart on the rear deck

and subs no idea
was thinking hertz single 12

amps I have
orion 425hcca with 2 bridging modules
alpine 3554 amp
sony crossover
phoenix gold eqx

and for the headunit I was gonna just use a RCA to 3.5mm jack to keep the stock am radio in there

suggestions please
