Ok, so I have a 2014 Cruze LT, no pioneer system. I am running a 4 channel amp for mids and highs. I upgraded the speakers to kicker 6.5 in the rear doors, 6.5 components up front. Everything in the stock location. I'm using an LOC for the stock h/u. I have been over everything and I cannot get sound to the speakers. At first I was getting some buzzing interference, so I know the speakers are hooked up correctly. I am on my 2nd LOC and having the same issues. No sound at all. I tapped off the rear speakers just before they go into the door pillar on both sides. I've checked all my fuses, everything is good. Anyone have any idea what I'm missing? I've never had an issue like this with LOC's in the past, but I've never had an upgraded amp and speakers, just subs. Thanks in advance!
