To connect four speakers to your Onkyo TX-SR302 receiver and ensure all are playing sound, follow these steps:

1. Check Speaker Connections:
- Connect the first pair of speakers to the FRONT SPEAKERS A terminals.
- Connect the second pair to the FRONT SPEAKERS B terminals.

2. Activate Both Speaker Sets:
- Ensure the A and/or B speaker indicators are lit on the display.
- If only one set is active, press the SPEAKERS A/B button on the unit or SP A/SP B on the remote to activate both sets.

3. Verify Input and Volume:
- Play an audio source and adjust the volume using the MASTER VOLUME dial or remote.
- Ensure the source is correctly connected and outputting sound.

If the second pair of speakers still does not produce sound, check wiring connections and speaker impedance compatibility.
