Weird Electrical Problem, so frustrating... Options

[tonytutino]

All of this started when i got my amp/sub put in last month on the 19th. (Its a 800w amp powering a JL 12inch W3) Well, a couple weeks ago i noticed my battery didn't want to seem to hold a charge and eventually it just quit. So i bought a Duralast Gold battery from Autozone on the 16th of December (having them test my alternator too which worked fine) and it worked great up until today. It just was dead when i tried to start it. Didn't leave any doors open, lights on, etc. so i took it back thinking it was just a bad battery, well they replaced it and tested my alternator again and everything checks out... As soon as i got the new battery i drove 15 minutes to work and that was it. i come out 8 hours later and its dead AGAIN!
I have no clue whats wrong... even if the alt. was bad, i don't see how driving just a few minutes on a battery would drain it... anyone know whats up?

I'm with lubu on this one. Sounds like your amp is staying on. When you turn off your car does the power light on the amp stay on? If it does either the amp's remote is connected to a constant power source instead of a switch or the relay inside the amp is stuck on. It's almost always just wired wrong.

Also you said you got a new battery and drove to work for 15 mins. A new battery isn't fully charged. It will take a couple of hours of driving or better yet over night with a slow charger to fully charge the new battery.
