Why is there like a bang only when turning off the car. Everything works fine and when you turn off the car then some kind of bang in speakers

Most car stereo’s have cap coupled amps some even with relay outputs, this could only happen legit if your stereo or amps are direct coupled, then you can get a dc offset thump. Cheers George
