500/1 JL Amp drains my batteries

flying143 · 29th October 2009, 09:31 PM

Hello, I am new to this site, and I was hopping that someone could help me out. I have a JL 500/1 amp in my truck. Long story short, I have discoverd that the reason my batteries keep dying is because my amp is drawing 2 amps when everything is off. I drive a service vehicle so my truck is parked during the week. I have to jump it off everytime I need to use it. Any ideas why my amp is pulling the 2 amp current? I opened up the amplifier and did a visual inspection, but I didn't see anything obvious.

Are you sure the voltage on the remote terminal is going to 0v when you turn the system off?

Do you have the signal sensing on or off?

I have removed the remote leat while testing, and it still pulls 1.8 amps. I do not remember if my signal sensor switch is on or off. i will have to check it tonight.
