I recently became a first time empeg owner. My previous stereo had been stolen and my insurance gave me way more than I paid for the old one, so I thought what better way to treat myself after dealing with the trauma of a theft than to buy myself a kick ass empeg.
Anyway, I managed to almost install it on my own. The only problem is, my left channel doesn't want to work right. The signal is coming through both channels from the empeg because I tried plugging in each channel into the right channel on my amp and they each work. It is when I try to plug either one into the left channel from the amp that it doesn't work. My amp was working before the theft, although they did try to steal that but couldn't get it out... they were a bit rough with it while trying though. Could this be a wiring issue up front? Any ideas will be appreciated.

Thanks.
