alpine amp m-450

Hey guys,

My amp does not want to work. It is getting 12v at the power and it turns on just normal and the light lights up normal blue. It does not go into protect mode or anything. The sub just wont play at all. I have checked my wiring a million times already. What could it be?

Thanks,

Mike

Dont know what head unit u sport but my alp has a option in the settigs to turn off/on subs fom the deck itsself, have u checked that ? , do u have a manual gain knob mounted around dash?? installed? most new amps have that option , mine was turned all the way down and i had little or no sub and was like wtf???? anyways hope my 2cnts might help good luck.

does anyone know why my amp wont work? Is it because I left it in my truck without any subs hooked up to it for a while? It was still connected and everything just not pushing any subs.
