Pop in stereo when turning off driving and fog lights

[dard6555]

I recently installed some PIAA 510 and 520's on my truck. When I turn those lights off, I get a loud pop in my aftermarket stereo. I have the light main power running directly to the battery. I also have the stereo amp power feed running to the battery. Any ideas on how to fix this popping issue?

 

Thanks

Lack of power perhaps? Or a bad ground. Check all your wires again for the install

Can anyone tell me where would be a good source of keyed power for the switches?

if you used a relay to control the lights then a microferade capaciter across the contacts would do it. if not then a pie filter on power input to stereo should fix you up
