my subwoofer is thumping with the idle of the car with the music on pause. with that being said it also gives a 10% single harder thump on top of the idle of the car when i use blinkers or windshield wipers or turn on/off headlights. i noticed all this after like 10 days after a shop installed a bypass for my factory amp. idk if they have anything to do with it but i read online it could be
Bad head unit
bad rca
bad ground
bad amp
some sort of loop
my head unit is a pioneer avh x3700bhs
amplifier is Alpine MRP-M650
subwoofer power akoustic 124x
any help is good help besides saying the power akousic is **** because i already know this.
