Just making sure the OP isn't going to try and connect a typical aftermarket amp or head unit directly to the factory speakers. His "new" stereo setup would be short-lived, particularly the tweeters!

I'm running an 8 channel DSP handling the crossover chores with 8 channels of amplification. I don't care for rear speakers, so I only needed 8 channels. The stock speakers sound REALLY good with this setup, except for the factory subwoofers. I'm using a single 10" sub in place of the factory subwoofers.
