Hi everyone. Alright so I went out of town last week and just came back today to find my car dead. I have an Alpine head unit (model doesn't matter) and a 15'' MA Audio Sub (MTX amp running close to 800 watts)
This isn't the first time that I've left for a while and came back to a dead car. The only time it didn't die was when I had to leave my car in a parking lot for a week, so I deattached the face plate for the deck. For future reference, should I deattach the face plate to save power?
