opinion's needed on my setup
 

2 kicker 12 inch L7's. dvc 4 ohm. running that with a fosgate punch 800.2 and a fosgate 500.1. both amps running so my subs gets the needed 750 watts. then a fosgate 800.4 to run the inside alpine speakers. changing my battery to optima yellow and also two 1 farad rf caps.
layout of trunk will be a flush box maybe plexiglass. amps will be on some sort of amp rack.

need opinios if the subs will be runned right. and if i should expect any problems

A lot of amps can be bridged together. But most would at least void the warranty. Unknown to me how this would affect the sound quality and reliability. I would get either a pair of medium output monoblocks, or one large monoblock.
