Need advice about shallow mount subwoofers!?

I have a 1987 chevy regular cab truck that I am putting a sound system in. I am thinking of using either rockford fosgate or kicker. 2 12 inch shallow mount subs. With either a 1000 watt kicker or rockford amp. Which is a better choice?? Will this sound system be loud and deep??Need advice about shallow mount subwoofers!?
I have 2 kicker 12 inch cvt shallow mounts in my reg. ford ranger. It bumps pretty good but goes for loudness not cleanness. The rockford fosgates go for cleanness. These setups are not made for spl or if you wanna be heard comin down the street. Also the box that kicker supplys their cvts with are bigger than rockfords so make sure you'll have enough room. and for kicker amps, they are known to blow up. If i could respend my money, id go for the rockford fosgates.
