Hello, I wonder how your AMP was wired! If it was done right it won't drain your battery... I have a 4 Amps in my Regal that I have not started nor drove for the last 3 months and when I went and started the car for the first time it was little slow and LOW to turn over and start but did start...

So there is a different issue or it is that the AMP was not wired right and maybe staying on all the time.

IF you are using your Cars OEM Radio it has or should have an Amp lead for the factory AMP. Be sure to connect to that for your Crunch Remote turn on. If your OEM don't have a REMOTE turn on you need to have a switch in place to turn on and off the amp...

If your using a Aftermarket Radio it could be that it is not installed right as well. Problem with the Impala's (Not that it really is a Problem) but they don't have a ACC wire and need to have that wire pulled to an aftermarket when the car has an aftermarket system put in if they don't use a Wire harness to connect to the factory wiring. NOW not all wiring harnesses are able to keep the ACC function so again it could be they pulled the wrong wire for the deck and it stays on even though the car is off.....

IF you have a Test light I would turn the car off.... Pop the trunk and leave all the doors closed.... Test the REMOTE port on the amp and see if the wire is showing 12V if it does without the Radio on then it is wired wrong....

There is NO reason that ANY Aftermarket AMP should drain your car battery while the car is off.... Also make sure there is no strays that should be going to the power wire touching the remote lead... The AMP Power is connected to the Battery... IF done right also it should (NEEDS) to be fused within 18inches of the Battery under the hood or if you Relocated your Battery with in 18in of your battery connection....

Hope you found something useful

Sounds like the OP has it hooked up right, as long as his Radio is not connected to a fuse or wire that is 12V Constant rather then Switched....

THe Acc on the impala is at the radio via a Data line, So unless a person buys a Aftermarket Wiring harness that retains that. The wiring harness would most times have an extra Red length of wire to make a connection at the Fuse box... The higher end Wiring harnesses will have the RAP ACC converted for use. So then it is Wire to Wire and no extra Acc wire because it is included.

About the amp being left on. IT could be that you had it hooked up right however if you don't use Spade connectors to connect your wiring to your amp if they are type with Screws and not push on. You can at times if not careful get a wire that can connect with a stray wire...

Also depending what type of Harness was bought it may or may not have Onstar or Steering wheel controls and the safety chimes for when you keep your keys in the car.. At times people just buy the one from WalMart that does loads of years from like 94 to 06 and so on. There are a lot of if and buts, What matters is that it works for the End User the way they want it to work.

Most times there is no fuse between the Radio aftermarket harness. I always add a fuse at the radio (Can be a bad idea because of how hard radios are to get out.) However because there is no protection between radio and amp Remote Turn on, I connect one so if it was to short to ground it don't kill the radio or the amp; it would pop the fuse. Most other fuses behind the radio is done by the Car and radios have them built into the unit or offer fuses on the radio side harness. Any power to anything should be fused. Also Main Power wire from Battery to the Amp should have a Fuse within 18" of the Battery, closer the better...
