Review on 🔊 Monoprice 108237 RMS 100W Outdoor Speaker Volume Controller - Gray by Michael Rosario

Yes, as another reviewer noted, the wiring is tricky. Inside there is little space for the input and output of the left and right speakers. I wired it up at the workbench and connected all the wires for the speakers. Like a wiring harness. Then I installed it outside and routed the cables to the speakers and amplifier. It's a neat setup with all the wires hidden and barely visible. I was proud of myself. Then I turned on the amp to check it. The volume control has a rotary control that locks at each of the 10 volume levels. As I turned the dial, I noticed that in two positions the right speaker is muted and I only hear the left speaker. I don't even think I'll be returning it because once installed it cannot be modified in the field. I would have to rip out all the cables I installed on the workbench and rebooted. I wish they would test these things before they sell them! (Or maybe they do and that seller sells the marriage.)
