I have... Pioneer Premier DEH-P680MP CDT HD-62 components in front CDT CL-69x in back US Amps XT 1600.4 Amp
My front left speaker keeps cutting in and out. When I first start my car everything is okay for about 10 minutes. Then that speaker goes out and possibly comes back in. I took it to the place I got it installed and they said everything looked fine. He told me to change a setting on my HU and this might fix it...but when I left it happened again. What could be causing this? Thanks
