battery drain on 95' celica GTS

[Crazyflip06]

hey guys,

I have just recently put in an in-dash video deck, and noticed that after use and the car sitting for no more then an hr, the car will go dead. I'm thinking its the deck draining the battery and was wondering if anyone knows whats the biggest size car battery i can put in, without doing damage.

Check your wiring for parasitic draw, The headunit should not be able to draw power without the ignition in at least the acc position. If it does check to make sure you have your wiring properly installed and that the ignition wire is hooked up as well as the remote wire, If you have an amp check t make sure the remote wire is installed correctly as well the the amp will constantly stay on and wont shut off when the vehicle is off if you dont install that wire as well.
