2000 watt Lanzar(shitty i know). It works, but only for low power, once i turn the headunit (pioneer) up to about 25, it goes into protect. It was working good, then a few days ago it just basically took a $hit on me and doesnt wanna give.
"Try moving the ground elsewhere and make sure it has a good solid contact point. What subs do you have and how are they wired to tha amp?"
This would make sense if he initially had a problem with the amplifier. He said it's no longer giving so I don't think a ground is the cause of the problem here.
I checked under the hood, and the fuse connection was melted on one side...2nd time this has happened. I bought a new one and replaced it, and it is still giving low power to the sub. (1-sub hooked up, shitty Audiobahn AW1200V)
