Unfortunatly a lot of comoanies will rate thier subs at a higher rms power than what is really appearant. Thats why there are professionals. Now these Power Acoustics have a good tone to them, due to the smaller cone and thicker foam. But truely they will not run with more than run running, and this is why. The PA 10"and 12" are both a dual 2 ohm coil. This means you can only run them in series @ 4ohms, or parrallel @ 1 ohm. now you have to make sure you have an "öhm stable" amplifier in order to run these to get the most out of them. If you decide to run two, no amp will push enough power to run them @4ohms and still give them enough power. Now at 1 ohm, it will run them fine, as long as your amp can handle the lowered impedience.
