If you are SURE the subs are exactly the same, and you bought the same model Pioneer as he did, something is broken.

Hook up the sub to one side of the amp, run it hard for a few minutes, then try the other side. That will test the amp and the sub, and verify that nothing is broken, and that you have a 2 ohm SVC sub.

Is there 2 sets of posts on the sub? red black and on the other side red black? If so it's Dual Voice Coil......
ok the sub model is swr-1221d. it has 2 red post and 2 black.
