check the resistance on your speaker leads from your box. if you get a reading then they subs are probably okay. if not i would pull them and check resistance at the coil in case they got disconnected for some reason

hook up a vom meter to the sub terminals on at a time (pos and neg) make sure the meter is set to detect Ohms. if you get no reading on one of the coils it is blown.

ohm meter, not vom. Digital $20 jobbers from crappy tire/target/whatever work great

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.
