Can i install a self contained subwoofer under the seat with the stock amp?

If you car is 2002 or earlier, the speakers in the door are already woofers and your stock amp is sending them only (or mostly) bass frequencies.

Radio-wise a 2003-4 car is apples/oranges different than an earlier 986, so we need to know what you have.

I did it again, sorry! 01' S with door speakers, no bose. So should i just opt for putting some 6.5 inch subs in the door and go with the rear speaker kit for some added audio?
