So as it turns out, I'm a HUGE moron and have been wiring my subs wrong. Single sub's havn't been bad, but I got two of these and wired them way wrong. I simply didn't understand... Doing the math on it, I had my dual subs wired in a way that brough the resistance to 1 ohm. These subs aren't rated for that... Neither is my 3000w amp. SO I had them wired in 1ohm, bridged on a 3000w 4ohm amp... They lasted a good 3 months like this, until they blew, and hit so hard my whole apartment hated me! (deal with it).
In the end. I got a lot more out of these subs than I was expecting, especially for wiring them wrong. Now it makes sense why my amp kept popping fuses... I've upgraded to Rockford T2's, and i'll see if the amp still performs after I rewire them correctly. Glad I caught this!
VERY impressed with these subs. Bought in a 4 pack. Other two were on a 500w amp.. so they're still healthy. Will rewire correctly and increase to 1000w. Definitely would buy some again.
