Monoprice 8 Zone Single Input Speaker Distribution Hub, Connect Up to 8 Pairs of Speakers to A Single Amplifier or Receiver, Black (138161)

I was really debating buying these or trying to jerry-rig some kind of terminal block or wire nut solution, and I'm so glad I just bought these. They are super easy to use, I just had to trim the existing wires a little bit to get them to fit, and everything worked great the first try - no shorts, static, or other weird issues. They're a bit pricey for what they are but I get that it's a niche product and it's definitely worth it in the time savings.

Works great as designed!

Good quality and sounds clear

Whoever wired our building speakers to our amplifier just twisted the frayed ends of the cables together and called it a day….so our speakers were always noisy and some places were quiet while other places were loud. This little device saved the day so that now all connections are secure and everywhere has the same loudness and less noise. Definitely worth it, and definitely more professional and reliable.

I bought it just to split one amplifier to power two sets of speakers. It works well. I took one star off because some of the connectors didn't work quite like they were supposed to, which just made setup take longer.
