The Sonos Amp should be able to connect to and power a third-party subwoofer, such as your JL Audio sub. If the subwoofer is receiving power but not being recognized by the Sonos Amp or the app, here are some steps to troubleshoot the issue: 1. Check the Subwoofer Output Connection Subwoofer Cable: Ensure that the subwoofer cable is securely connected to the Subwoofer Out port on the Sonos Amp and the input on your JL Audio subwoofer. RCA Cable: The Sonos Amp uses a standard RCA connection for the subwoofer output. Ensure that you are using a quality RCA cable and that it is fully inserted into both the Sonos Amp and the subwoofer. 2. Subwoofer Settings on the Sonos Amp Subwoofer Level and Settings: Open the Sonos app and navigate to the room where the Sonos Amp is set up. Go to Settings > System > (Your Room with the Amp) > Subwoofer. Ensure that the subwoofer is set to "On" and that the crossover and volume levels are set appropriately. If the subwoofer is recognized, you should see these settings available in the app. 3. Subwoofer Configuration JL Audio Subwoofer Settings: Check the settings on your JL Audio subwoofer itself. Make sure that it is set to the correct input mode (e.g., LFE or Line-In) and that the subwoofer’s volume is turned up. Crossover Frequency: If the subwoofer has its own crossover frequency settings, make sure they are set correctly. The Sonos Amp typically handles crossover internally, so you may want to set the subwoofer to "LFE" mode if available, which bypasses the subwoofer’s internal crossover. 4. Power Cycle Power Cycle Both Devices: Turn off both the Sonos Amp and the JL Audio subwoofer, unplug them for about 30 seconds, and then plug them back in and power them on. Sometimes a simple reset can help establish the connection. 5. App Update and Firmware App and Firmware Updates: Ensure that your Sonos Amp and the Sonos app are running the latest firmware and software versions. Sometimes connectivity issues can be resolved with a simple update. 6. Check for Subwoofer Signal Subwoofer Signal: Test the subwoofer by connecting it directly to another audio source (like a receiver or different amp) to ensure that it is producing sound. This will help confirm whether the issue lies with the subwoofer or the Sonos Amp. 7. Check the Subwoofer Port Subwoofer Out Port: Inspect the subwoofer out port on the Sonos Amp for any physical damage or debris that might be preventing a proper connection. 8. Consult Sonos Support Sonos Support: If none of the above steps resolve the issue, it may be necessary to contact Sonos Support for further assistance. They can help you diagnose any potential issues with the Amp or the app. By following these steps, you should be able to determine whether the issue lies with the Sonos Amp, the JL Audio subwoofer, or the connection between them.
