Hey all, i'm hoping someone can help me out here. I recently realized that both my front and back left side speakers on the driver side of my 2001 VW Jetta don't have any sound coming out of them when i have an auxiliary input hooked up. They work fine with CDs and radio, though. I had a Sony head unit installed by Circuit City about 1.5 years ago so i would have an AUX input port easily accessible so i could hardwire my iPod, and it's worked fine since they installed it with various iPods and my iPhone, until now. My iPhone plays out of both earbuds, so I don't think that's the problem. Does anyone know what might be causing this?
