If you're still looking, I have a couple inexpensive systems.

First is just for bass...2 12" subs, 400w amp, enclosure, and wiring kit for $315. Its good stuff...Distinct Audio (made by Crossfire). I had a complete distinct system in a 94 Caprice wagon I sold, and we've put a couple in customers cars, with nothing but complements.

If you stay with the factory deck, you'll need a converter. A decent one is about $30. A really good one can be over $100. As others have said, buy a deck. I sell a DUAL AM/FM/CD/MP3/WMA with RCA pre-outs (and deck power) for $175 installed. You could run the factory speakers on the deck power, and run the RCA's for the subs. When you upgrade to more amps and better speakers, you're still in good shape.

Second is the above bass system, with an AM/FM/CD/MP3 player, a second 400 watt amp, and 4 coax speakers for mids and highs. $1100 installed. Again, Distinct and Crossfire.

I am an authorized dealer for Crossfire, as well as Pioneer, JVC, DUAL, Audiobahn, and Lightning.
