Subwoofer stopped working

[JPVortex]

Hello yall, today at a stoplight my sub stopped working out of nowhere, just like it turned off. There is power going to the amp and it seems to be okay upon visual inspection.

Theres continuity in all of the wires so no breaks there.

I took the sub out of the box, it's a 4ohm box. I tested it and it's a bit high at around 4.8ohm. Does this signify a blown sub?

Noticed here and there the sub makes a tiny little pop. I think its blown

Is there voltage coming out of your amp to the sub?

Oh **** I tested with a test light the 2 wires going to the sub from the amp, no power at either of them

Then it sounds like an amplifier problem then. Not sure if that's worse or better!!! Lol

Does your head unit have an on/off setting for the subwoofer pre-outs? If it does and you lost battery power, it might have reverted to default settings and shut them off. Just thought I'd mention that before you go switching amps, I've seen it happen before.

EDIT - Just remembered you said it quit playing while the truck was running at a stop light, probably an amp issue.

Yeah amp failed. No power going to the sub. The green status light blinks like every 10 seconds and the sub makes a small noise. That light should be constant.

It has power going in and cleaned the ground to no avail.

So my sub RMS is rated at 50-150.

So for my new amp I should get something close to that range right? It's hard to find something with a low enough RMS for it, but I found a Rockville one thats rated at 200RMS.

Heres the link: Link
