Audio Systems: Bass System, prefrence, kindof

Question
I'm lookin for a car system that has alot of bass, any suggestions on what subs, amps,speakers, etc.  

Answer
Pardon me but I really dont like answering questions like this.  picture yourself a car dealer and its your job to pick the right car for the right person and the right job.  and someone walks in and says "I want a car with really big tires"  It doesnt allow the car dealer to match up exactly what the person wants. that's kindof what this question does to me.

What is your budget for the subs/amps, wiring etc?
How much space are you willing to give up?
Are you going to install it all in the trunk or rip out the rear seats and build a wall?
Are you building the box and if so do you have box building experience?
What type of vehicle is it going into?
What type of music do you listen to?
Whats your prefrence between loudness and clarity (need lots of both or sacrifice a little of one for the other?)
Are you changing the cd player out or is it factory?

sorry but I'm here to help people get the most they can and frankly that's why you're here too right?  so if you dont mind answer these questions and we'll get started.
