2015 GT, Shaker Pro Audio 12 speaker with subwoofer..... Always on, why??
Noticed the other day after the car was shut down with the trunk lid up to get the groceries that a hissing or white noise sound was coming from the sub woofer. The car had been turned off including the radio and sitting for ten minutes yet the sound was still there.
Is the sub woofer supposed to be powered up all the time?
