no. there are many things that can blow a sub, but the most prominent cause is user stupidity, also known as "user error" in the customer service world (mine's more accurate). use the gains right, put it in a decent box, and wire it correctly, and you should be fine.is it going to blow them or damage them at all?
if you bridge them, you'll be at either 1 or 4 ohms. you'll have to do it at 4 ohms on that amp.should i just bridge these things or what???
