When I started my car today all the speakers were popping like the amp. was trying to start up. If I turn the volume up the radio still plays but the popping is in the background. If the radio if off there is no popping. I have no clue why this has started or how to fix it. Any suggestions on what it could be or how to go about fixing it?
Also, I don't know if this could be relevant but, I recently had a new alternator installed.
Thanks for any help!
