I need to figure out if its my sub thats blown, or my amp that isnt putting out power. The amp turns on, but nothing happens. Is there a way to use a DMM to check for power output to speakers?

Plug the dmm into the speaker outputs. Check voltage

No power when testing with a DMM through the speaker terminals =[

Signal to the amp? Any lights to light up on the amp? Checked the ground? Checked the fuse for your power wire?
switch the DMM to DC, you should be getting something between 13-14v for the power inputs. switch it to AC, and you should be getting a reading from the speaker outputs.
make sure your ground is secure and like trancer said to check any fuses that may have blown

9V battery is easier and works just as well //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

That is the perfect spot to do that. OEM sub may interfere with the new one and cause cancellation.

But then you could just use the volume knob to rather than pay for earplugs.
