So I go check on my boat (06 Supra 21V) today after the freeze this week in Dallas, TX to make sure everything is OK. Everything looks good until I turn on the stereo and my Left 2 tower speakers (JL Audio) are humming like crazy. I turned down the volume all the way and the noise is still there. As soon as I turn the stereo switch off, the noise goes away. Only the Left Tower speaker cones were vibrating like mad even with the volume all the way down.
Any ideas what could cause this?
It was working fine last Wednesday when I pulled the drain plugs, etc on the motor and V-drive for the freeze.
Any help would be appreciated.
Thanks in advance.
