I can drive around for a little bit or a little while...doesn't matter when, where, weather, or anything...but i'll listen to my stereo in the truck and it's all stock, come home, power off radio, HVAC, and then shut truck off, and shut my door and walk away hitting the remote lock and my speakers pop real loud...any clues??? hell sometimes it pops before i get out of the truck, but is always after i power radio and truck off...
