what do u think it could be then because my sub dosent make noise and my amp ligts up

Check the wires going to the cone of the sub from the connectors if they are loose it wont work and you would have to sauder it back together

I know when I roasted one of my subs, pushing on it would result in a scratchy/grindy type noise, and my new subs don't do that. Try that out.

start with the easiest things first

step one: see if your speaker wires are securly connected to the amp

step two: lightly push in on the cone and see if the sub feels like it is rubbing

step three: pull sub out and se if wires are connected securly to sub

step four: check coils with dmm(and look to see if tinsel lead is disconnected(dmm will tell))

or if someone has been toggling with ur setup, the gain could be set to none.

One way that I check it is if you push the coil in and out, you should'nt hear anything, but if you hear a scratching sound , then most likely your coil is fried
