okay, so when i turn the car off and take out the keys, the car's speakers still make a noise. i disconnected the battery and the sound stopped. im a little afraid its going to kill the battery. im hoping someone can help me.

 

need a little more information. Is this a custom install? just sounds like the head unit isn't connected to a switched wire.

 

its the factory setup. i unplugged the connector with all the head outputs from the amp and the sound went away. im not all that good with electrical/radio, but imo it seems like the amp is constantly being powered.
