I have a 2002 MDX , I had a Kenwood touch screen stereo installed at best buy they soddered rcas to the wiring harness for the speakers and now I only have sound on the passenger side and nothing on the driver side. Before the stereo was installed I had perfect sound. I was told it could be my amp so I ordered a new one but Im not really sure if this is the problem, anyone have any ideas or have had this problem before?
