Hello, I recently purchased a 2004 Nissan Pathfinder SE with the 6 speaker Bose system. I am planning on installing my Sony XAV-AX1000 with my Kenwood X301-4 amp and Kenwood (KFCX694) speakers (installed in boxes). My plan is to rewire the speakers with better gauge speaker wire to the amp and completely bypass the factory Bose stuff. The Amp is 4 channel (so only 4 speakrso I was wondering if there was a way to have 6 speakers total working, 4 connected to the amp and the other pair somehow just running off the receiver. Or maybe I can run the front and rear door speakers off 2 channels and then the Kenwood speakers off the other 2? Then I'm not sure what to do with the tweeters. Thanks.
