My buddys deck drains his car battery when his car is off and key is out...

Anybody know what the problem could be?

 

Bro, What did you hook up the power wire to? Or should I say, what did your buddy wire the power to?

 

Go through the wiring harness and double check everything. Make sure all of the wires are connected where they're supposed to be. Sounds like the red wire is either connected to the yellow one, or it's connected to another constant 12v source.

 

Yea Bro, wiring sucks, but you gotta make sure all the wires are in the right places Bro. Yor never want to hook up the power wire to a wire that is directly hooked up to your battery Dude, otherwise you will continue to experience this problem Bro. Elementary.

 

False info there. Some of the higher end screens require a new wire straight from the battery for both the power and ground. They draw too much current for stock wiring. You can do it, you just have to know what you're doing and think about it...

 

ok thanks, ill see if this helps
