having problem radio wiring. i bought the wiring harness so i wouldnt have to cut any of the factor wires. when i hook the my new radio up, only 4 of the speakers play (the front and the 4x10 in the back). when i hook the factory radio back up, all six of them works. nedd help tryin' to figure this out

What's the stereo type and what type of connector did you buy?

cc-2014 general motors 1988-up (21pin) its the right one. i hooked up hundreds of radios before and never had this problem

I think the reason he asked was there were two factory setups, one with 4 speakers and the other with 6 speakers. Easy mistake, but one you probably wouldn't make.
