We also recently bought a 2010 Sahara and the left rear speaker (in the sound bar) doesn't work. I've switched it to the rightside wires and it works fine, so I know it's the wiring. My question is, is there a connector between the front amp and the sound bar or am I going to have to replace the whole wire from amp to speaker? I've never really messed with amps so I'm a little cautious. Anyone got any advice?
