has 2002 Impala head unit.? Reason for asking: With deck amp staying on all the time, it drains my battery overnight and then of course, I can't start the car. Anyone know whats going on? I don't want to just start replacing things that might not be broken...

make sure he didn't install some kind of bypass switch, what stays on, a small light, or the whole unit?
