[QUOTE="Jonthesharp, post: 8580018, member: 673280"] The battery went dead in my wife's car right after I installed a sub and I am trying to prevent it from happening again. I checked the remote wire with the car off and it had 0 volts I checked the positive to ground on the amp with the car off and it had 12+ volts (as seems expected) I disconnected the remote and the ground wire and tested the positive terminal with the ground terminal (not the wire) and it had 3-4v. This was also true with the positive disconnected. It would eventually go to zero over time. I assume this is the capacitors losing charge, but I am worried that its leaching power off the battery when the amp is off. Can anyone confirm if this is normal or if there is an issue going on here? Thanks [/QUOTE]
