First I took the Bose headunit out using the din keys. Easy enough. Then i disconnected all the plugs from the back. After doing this, I couldn't find the correct wire diagram anywhere for what I was seeing. Off to Google I went and found out about the Bose amp underneath the front passenger seat. I didn't want to have to buy some adapter and then figure out how to connect that. So I decided that I'm going to install new speakers and rewire myself. But running wires from the door to the head unit was not working out for me. So I unbolted the 4 bolts (2 in back, 2 in front) that hold the passenger seat down so I could have easier access to the Bose amp. After taking the door panels off to put in the new speakers I knew what color wires were used for each speaker. So I found those same color wires going into the Bose amp. I cut them and spliced with speaker wire I had bought for around $20 at Best Buy. After splicing it, I ran the new wire from the amp to the back of the head unit. Works great!!
