I installed a MyGIG RER into my 2005 WK and have had no problems for three years. Suddenly there is so more sound/audio. Checked the fuse and it's fine. I have an autistic daughter who absolutely slams the rear door every time she gets out. If a wire connected to that speaker came loss could this cause the problem? Could this also be an amplifier problem? Has this happened to any of you guys? Any help or ideas would be greatly appreciated.
Did you install it in your 2005 with a lockpick? If so, unplug the lock pick wire from the actual lockpick (not the radio) and plug it back in while the Jeep is off (no need to unhook the battery). Happened to me twice while I had mine and the sound came back both times.
