Car Stereos: aftermaket sound system, accessory source, amplifier

Question
What does it mean when your sound system kills your car over night even if eveything looks turned off? What do I need to do to get that fixed?  

Answer
Hi Jenifer,

It could be any number of things.

The first thing I'd check would be if whoever added the sound system to the car jumpered the 12V constant to the amp remote turn on.  This would cause the amplifier to be on when the car is off.

If it is, you'll need to get someone to run a fresh wire from an accessory source to the amplifier's remote so it knows to only turn on when the car is on.
