Metra HS-SS4 4-Zone Speaker Selector.

Distribute a stereo speaker-level signal to multiple listening zones with the Helios HS-SS4. This Low Profile 4 Zone Speaker Selector features a manually activated impedance protection circuit, accommodations for 14 gauge cable, and in-wall installation options. To prevent impedance to the amplifier from dropping below 5 Ohms, simply switch the protection function ON. It can also be turned OFF when used as part of a system incorporating impedance matching volume controls. The terminals at the rear of the speaker selector will accommodate up to 14 gauge cable; sufficient for cable runs exceeding 100 feet. For shorter distances 16-18 gauge cable suffices. CL-2 or CL-3 rated cable is recommended for compliance with local building codes. When connecting a speaker and amplifier, maintain polarity: positive to positive and negative to negative.
