Depending on the type of enclosuer, yea they're powerful. But only if you supply enough power to them, so knowing that, you'll most likely have to get a HO alternator and do the Big 3 also. But to answer your question, yes, because I have a friend who has just ONE of those subs, and it blows my 2 ProAcoustic PWRO-122D (12") out of the water.
