I have a 2000 mc ss my battery has been draining overnight. Has been pulling the radio/amp fuse lately and the battery has not dying. Use a multimeter and read out a 1.50 amp drainage with the radio/amp fuse in. When i pull it out i get a 0.5/0.6 amp drainage. i was told that it would be the factory amp, but just recently replaced it with another factory amp. Do anyone know of the radio causing this problem?

 

I have been doing some troubleshooting myself. So here is what i have done,because i know its coming from either the radio or amp, i would leave the fuse in alone with the amp and do a meter test and it would come out around 0.5/0.6 amps draw. When i reverse it with the radio in and fuse i get around 1.5 amps draw. With both and the fuse i get about 1.7 amp draw. And that 1.7 amp draw i am not sure if that is a normal draw because of the radio memory and the security o the radio and the other functions of the radio.
