Ive got an 03 with the bose system. My plan is to rip out the stock headunit, replace it with a double din. Put new components in the front and coaxials in the rear, and have 2 amps. One for the speakers and one for the subs. So i will not be using the bose system. I read a post on the diesel place about all the different harness's but am a little confused? I dont have on star, and dont want to keep anything bose. So do i need the Pac C2R-GM24 OR Pac OS-2CBOSE? Thanks in advance!
