Speaker upgrade will make a HUGE (like as big as bondo's ass) difference.

I would go with a decent coaxial speaker (tweeter mounted in the middle). Do not go overboard, I would think you can scorre some decent speakers for about 30-40 a pair. Or maybe alot less, I have not priced car audio recently.

Do not go with big power handling speakers, as they will likely need more than your amp can push. Just about any aftermarket speaker with a plastic cone and a seperate tweeter will be light years ahead of the stock paper cone speaks.

I bet you have a walmart or similar that will have some cheap off brand speakers real cheap. Or hit up ebay, etc...

Crutchfeild.com will have a chart or something to tell you the speaker size.

As for added bass, well a powered 8"-10" sub will be the best bet. Many will allow you to just tap into existing speaker wires for signal.

Do you have the factory head unit (cd paler, tape deck, 8track, etc)? Or an aftermarket unit? Yeah, I just asked you about your unit, live with it.
