2014 Silverado Speakers not working after LoC install

[Steven Kubasti]

I recently installed a line output converter, amp and subs in my 2014 double cab. It’s a non Bose model and I taped into the drivers side rear speaker wires in the B Pillar for the LOC. Upon completing the install, both front door speakers and the drivers rear door speaker stopped working completely. The front dash tweeters and passenger rear door speaker still work. I completely reversed the install, removing the LOC completely and Im still getting no sound. Did I short out something? The entire install was completed with the battery disconnected.

You may just need to insure the connections are solid. I solder or use a solder in a tube from HD. You can apply it and heat the solder with a mini torch. 

 

What wires did you use to connect the LOC?
