2-Way Audio Stereo Speaker selector Switcher Box, Combiner Multi Zone A B Speaker Switch Distribution Controller Box - P21

Ran four speakers at the same time through one amp and was concerned not to damage the amp. Little fiddly dependent on the thickness of your speaker wire but small enough to be unobtrusive. Performs well. Very pleased.

Works well good quality

I bought this to replace the prior one I had, you'll find it on Amazon for around £10, that just did not work. This works perfectly, is very compact, well made, and switches without a glitch. Recommended

Works brilliantly, very easy to install
