I am looking for a sub-woofer setup but I dont want to change my factory cd player. If any of you have this please give me some input on setup,sound quality,and is it worth $700 or should I just buy the enclosure and supply my own sub and amplifier? Thanks in advance :)

The BSW stuff is pretty good from what I've read. There are plenty of threads where people added subwoofers. I personally went the route of getting my own enclosure, sub, amp, etc...
A quick search in the stereo forum should help.
