as far as amps and pricing go, the going rate for quality is a buck a watt. and as far as power handling, better quality subs are more efficient, which means that as well as being able to handle large amounts of power, they can also operate on less. if you've never had a big sub in your truck, you are gonna have lots o thump with even 200 watts. but a good quality amp making 800 plus watts with the gain turned down is going to do the same thing, but much more easily. it's like turning 35 inch tires with a v-8 versus a four banger. they will both do it, it just depends on what kinda life you want out of your components. i would go with the 400-800 watt range, and use a dual channel bridged amp, as that's gonna be way cheaper than one of the big monoblocks, while giving you more wiring options. send me a pm and i will send you some sample wiring diagrams.
