You'll need to pick up two high level converters which will tie into your factory speaker leads converting the speaker level into an RCA signal. Being that you are using a 4-channel amp, you will need two such as:

You wont be too impressed with the sound if you use better speakers with the original HU. The manufacturer generally matches up stuff so that they sound good. I see a new headunit in your future.

 

I disagree. I have upgraded all the speakers in my car still using the factory Non-Bose head unit and am quite happy with the sound quality. Granted, I'll end up upgrading to a DVD setup in the future, but I am not complaining about the sound quality whatsoever. My $.02
