[QUOTE="John_E_Janowitz, post: 5855713, member: 550657"] Well you can plug the woofer directly into the wall, but all you'll get out of it is 60hz. How much power is applied then is determined by your breaker and the woofer resistance at 60hz. V = I * R so if your resistance is 4ohm at 60hz you'd have 30 amp applied with 120V circuit. P = I^2 * R so 30^2 * 4 = 3600W. I wouldn't suggest doing this for too long with most woofers.
