Thanks for reaching out. 👋
I would recommend checking out the SA-5 Amplifier. This is SoundTouch ready and is designed to power speakers, including outdoor speakers.
You can see our range of outdoor speakers here (make sure you tick the 'outdoor speakers' box.)
Be aware, that with Wave systems, you can only send streamed sources to other speakers around the home, you cannot send AM/FM radio, AUX or CD audio.
