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?
9V battery is easier and works just as well //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gifyou can always use some wire and touch one set of terminals, at a time (if its a dual vc sub) to your car battery. if the cone moves, the subs fine.
