12" w7 sub problem

[Stephenc44]

To be honest...I don't even know what half the knobs on the back of the amp are for?? Maybe i've messed with one of them on accident?? not sure if that would cause it ( if you couldn't tell i really don't know much about it haha)

You didn't respond to what kind of amp is it, class a/b, d? D's are more effecient and stay cooler and A/B pull a lot of power in most cases and got very hot. My amp did the same thing, where it would cut in and out. Was going into protection.

Class d

Humm, those generally stay cool and don't overheat to much. Maybe a ground problem? Check all the connections? Maybe someone with more knowledge on the sub could help. I really thought it was an amp problem, which it still could be.

What kind of car do you have? A 1000/1 can draw a lot of current, and I say that chances are, your car's voltage is dropping too low.

You know, i've had problems with my car battery actually. I've had to jump it a couple times. I have it in a 2002 Escalade. Anytime i leave the car stereo on without turning the car all the way over it almost always won't start back up..

Yeah, looks like a weak electrical system is your culprit. What size wire are you using, and how old is the battery? You might want to look into a new, beefier battery, and doing the Big 3 (If you're not sure what that is, search for it) Make sure you're running at least 4awg power and ground wire, and make sure your ground goes directly to bare, shiny metal.

Frame if possible

Not sure on the wiring...i just recently got a new battery installed...but i'm pretty sure it wasn't anything beefy...just got it serviced at a local station.
