    2. Install each lyriQ Keypad in a single-gang box after connecting a pair of speakers to each keypad with 16/2 speaker wire. Also install the lyriQ Local Source Input in its single-gang box.
    3. Install the lyriQ Single Source Four-Zone Distribution Module in the On-Q enclosure and connect the Cat 5 cables from the keypads and lyriQ Local Source Input.
    4. Run a Cat 5 cable from the lyriQ Single Source Four-Zone Distribution Module to a single-gang box containing the lyriQ Flush-Mount Single Source Input, and connect the audio source to it with RCA cables.
