Just got my 99' G20 Today! Best car I have ever driven, even better then the 98 Mercedes E430! I am an avid car stereo enthusiast. I had a Clarion head and 6 Infinity Reference Speakers run by 2 Kenwood Amps, 2 12" JL W3 woofers run by a lightning audio 500.2. I took all this out of my old car and I am wondering what to do.
I think that the Bose System sounds pretty good for a factory system, and I was wondering if anyone has changed theirs and if so what did they do. I think if I was to do anything I would put in a Clarion Head Unit with JL speakers. If you people who have changed them, how much better did it sound? Was it worth it?
Thanks for any info you have.

i changed mine out went with a alpine mobile video head unit polk momo compontes front and rear with two 12 momo subs being ran by a mtx 1000 watt rms mono block amp and my compontes are being ran by a mtx 4 channel and a 10 disc changer bose is good but nothing compared to the polks i went ahead and replaced all my wirning because the wiring bose uses is different from a normal head unit and have it all hooked up with streetwires 5.0 zero noise rca's so no distortion from the rcas and a streetwires 1farad cap

I definitely switched out my stock system.. heres what I have now.
