If you know what Coil configuration your subs are, you can disconnect from the source/amp, and use a DMM to check the coils,to find out if its blown or not.Very easy to do.You can YOU TUBE it up, and watch a tutorial on how to do it,easier than explaining it to youMy sub box only plays one sub when I connect them both the amp will go into protect mode. I checked all the connections they were fine, and my left sub plays fine. When I connect the right one by itself, it doesn't play is it blown? Is it time for a new setup? I've had this one for about 2.5 years
