is it possible that an amp can drain my battery like over night, as my other thread said i just installed 2 10" JBL 1000Watt subs
and i went to work out this morning and when i came out my car wouldnt start
so i disconnected my subs from my amp so it doesnt send any power and need any power and gonna go to my local speed n sound store and see what they say, but i was gonna try here first
thanks

It's possible if you hook the amp up in such a way that it doesn't turn itself off when you turn off the head unit or the car. Several years ago my friend had an amp that would not turn off automatically when he turned the car off, it would stay on and kill his battery, he had to remember to shut the head unit off BEFORE he turned the car off the signal the amp to turn off.

If you hooked the amp up so that the main power cable is hooked up to or touching the remote turn on post, then the amp will always have a 12V signal on the remote turn on and always think it should be on. Hook everything back up and turn the car off, then look at the amp, is the indicator light on? If so there's either something wrong with your wiring or something wrong with the circuitry that turns off the amp when the HU/car is off.



EDIT:
also note that just disconnecting the subs from the amps will not keep the amps from consuming electricity. It may be slightly less, but it will in no way save your battery from being drained. Your best bet is to pull your inline fuse (you do have at least one fuse, right? I have three between my bettery and my amp)

Check your remote wires. Something may have been wired wrong and a constant power source could be running to the amp rather your remote power.
Another quick solution that you can try is installing a switch on the power wires so that you can manually shut it off from inside your car.

i dont know, all my wires are under carpet and the amp and wiring and old subs came with the car, and my amp has a fuse, can i just pull that out until i get the problem fixed?

yes pull the fuse out until you can get it to a shop or something and have someone look at it. Trusting someone else's wiring may not be the best idea either. Do you know what guage the wire is? Sometimes it'll say on the insulation. It sounds like you have two power hungry amps there. If you are running like 8 guage power cable to it or something that won't be nearly enough.

um i have one amp, 2 subs, and yea, i know absolutely nothing about sound systems so yea, im gonna go pull the fuse out of the side of the amp and let my shop take a look at it, i know more about performance then ice, well il let u guys know what they tell me
thanks for the help

by fuse I meant an inline fuse in the main power cable, you should have at least one, it is usually near the battery (with a foot or so worth of cable from the battery to it). If you don't have one inline you really need to get one SOON. at least one. like I said I have three fuses between my battery and my amp. That is not including the fuses in the amp itself.

yea, well i have i think 1 or 2 of them between the battery to the amp, well to cut the power to the amp completely so it doesnt drain any power from the battery i took the fuse out of the amp until i get to the speed n sound store today, im goin in like 30 minutes, its just that i dont want to have to buy another new battery anytime soon

in case it was not covered, your amp will not draw ANY current if it is not on, however it WILL draw maybe between 1-3 amps if it is turned on with no load (ie. idling)
