Not sure what the deal is with these subs. They were hooked up to a Rockford Fosgate P5002 at 2ohms on each channel (this may not have been the best way to wire).
The amped was used from eBay. It kept overheating and blowing fuses, possibly becuase I was attempting to draw too much power from the amp (800 watt subs, 500 watt amp).
Anyways, so, now they produce no sound. I dont have the amp anymore. Doesnt look like any connections are loose on the subwoofers. Coils dont have any burnt smell or bad cone resistance. Other than that, I dont know what to check for. I believe its an easy fix...
