I’m attempting to install rear speakers in my 2018 Chevy Spark LS, we got the amp installed along with tapping into the front speakers and have the ground and power hooked up but something is not working right..either my car will play music for a good 30 seconds and then cut out completely or it won’t play music at all and just make a constant buzz from the 2 front speakers. I figured if I could get the color codes for the wiring and/or pin-out for my vehicle then we can just directly connect to the head unit. Any advice? Tips?
