Speaker "growl" on start





) The previous owner removed all the stock audio. components and installed a "very" complete Alpine system, which i had to straighten out professionally. If the stereo is on when i cold start the car, or if I turn it on after starting the car, i get a growling type noise from the rear speakers. It usually lasts longer the colder the weather, but no longer than 3-5 seconds. Im trying to avoid explaining this to a potential buyer. Thank you!
