Hi, i have a 07 acura tl and wanted to install a aftermarket subwoofer and amp for a little extra bass. I didnt want to mess with the back of the navi/radio so the place i went to installed a hi/low switch. Everything seemed fine until i drove away then when i lowered the volume the subwoofer kept humming then when i pressed the gas it would stop. I brought it back they re grounded the amp but its still there. What can it be, they are trying to tell me itsd the amp or subwoofer but its not they are new. any suggestions?
Subwoofer humming with radio volume down?Goes away when step on the gas pedal?
