I had everything completely connected before reconnecting the battery. When I turned the radio on, it was booming badly. I turned bass knob down and made a very small difference. I started checking it out and started unplugging and it stopped the booming and started sounding normal when I removed the plug from the amp. I have not had time to follow up due to the storms!Do you have both ends of the cable plugged in. I.E. control knob and sub plugged in. I know when only the sub end is plugged in the sub will make odd low ruble sounds.
