As to bass response in the front speakers and the overall performance of the sound system, here's a thread that has discussed tweaking the stock system. It's very detailed and actually works!

I'd replace the speakers with same like and kind and do the suggested mod from the link. THEN ... pass judgment on the sound system. I did the mod and run my bass at +2 (CD) and +4 (radio). I have a friend that does car stereo custom installs and he's quite impressed with the stock system. Now as to the Becker head ... that's another topic.
