Did I blow the sub or kill the amp?

[Smeech]

I have a Lightning Audio 2-channel amp paired with one Alpine Type S sub. I've had it installed in the stang (to the stock mach 460, with rca converter) for a while and had it in my old car before that. Last night, I was slumping E-40 "Muscle Cars" and all of the sudden smelled a burning smell, and the sub stopped hitting... so I turned off the system. Today, I turn it on and it seemed to work again, but then the Protection Light comes on after a few minutes and the sub stops working.

Tonight I tried it again, the sub didn't sound so good and the lights were dimming bad.

There's no other problems with the car starting, so I don't think it's the alternator.

I think I messed up the amp, because the protection light is coming on. But why would my lights dim so bad? The other thing I was thinking is that I could have blew the voice coils on the sub?

Maybe it's just a connection problem, and a coincedence...any thoughts?

hook up a diff speaker on the amp and see what happens that will let you know if its the amp or the sub, if everything is fine, then somehow you blew the sub

i think you prolly toasted your amp just a lil bit.

Might be a voice coil. If a voice coil goes, it may lower the impedence of the amp load and cause the protection to come on.

Yeah most likely the sub is half cooked causing a low impedence situation on the amp. Because the amp's not designed to run high-current loads it's messing up on you.
