- Connect speaker cables from the rear speaker terminals to the rear speakers.
- Ensure the speaker cables are securely connected to both devices and follow the recommended wiring pattern (positive to positive, negative to negative).
Step 3: Calibrate the Subwoofer and Rear Speakers
- Set the subwoofer to the “On” or “Auto” position, depending on the model.
- Adjust the subwoofer’s crossover frequency to match the rear speakers’ low-end frequency response (usually between 80-120 Hz).
- Use a calibration DVD or Blu-ray disc to test the surround sound system and adjust the rear speakers and subwoofer levels accordingly.
Tips and Tricks for Optimizing Your Surround Sound System
To get the most out of your surround sound system, consider the following tips:
