I have a new 200w stereo receiver from Sony. I connected this speaker to the receiver and then to the outdoor kicker speakers to the subwoofer according to the instructions. The built in crossover didn't seem to do anything as the outside speakers sounded the same, which is fine, but this speaker had almost no bass and you could still hear higher pitched voices trying to play out of it. Very disappointed in him. It may need a dedicated subwoofer amp, but I think 200 watts is enough and there's no mention of needing one. Maybe I got a defective one? Make sure you test it and are happy with it before running cables and burying it. I'm glad I did. I found an old 8" RCA 60w active subwoofer and just hooked it up with the speaker wire that went to the satellite speakers and it blew the thing off. Again, maybe mine was defective?
