Ok recently one of my battery lugs came loose while i was driving which made every thing acting weird and the music kept cutting out anyways after that i secure the lugs and all connections but my taramps md5000 keeps going into protect with the car off....the weird thing is with the car running its good.I carried it to the repair shop in my area and the guy found nothing wrong with it and saying my battery probably got damage and cant handle the load of my amp which i find it hard to believe...my red top optima although aint the best it rest at 12 volts but it starts the car fine so idk whats up...
