What can cause your aftermarket stereo to cut off and turn off?
The problem is often in the speaker wiring. A break or crimp in the speaker wiring, often where it passes into a door, can cause the sound to cut off entirely. The problem could also be a bad amplifier or bad wiring to the amplifier.
Should you turn off radio before turning off car?
If your car radio won’t play music unless the keys are in the ignition then switching it off when parking will not make any difference to the battery drain. However, if your radio is wired to continue to play when the keys are removed then do switch it off to prevent excessive battery drain. Save this answer.
