I got these to use with a TV for music outside this room to the swimming pool, but these are 500 watts, my TV is only 60 watts. So, I have ordered a surround sound system, (600 watts) to plug into my TV, and then to these speakers, only way to get them to work for me. So, just remember this is you want to hook to an existing system, the 500 watts. I wish someone had told me, but no problem , my kids want the sound outside where they can hear the music from in the swimming pool. They are up high on a black board as a background, they look good. We'll see next year how well they held up.
