There are a few different reasons why your spectrum volume might not be working. Here are some possibilities to check:
1. Make sure that the volume on your device is turned up. This seems like a simple fix, but sometimes we forget to check the most obvious things first!
2. If you're using an amplifier, make sure that it's turned on and set to the correct input.
3. Check all of the cables connecting your components to make sure they're plugged in securely. Loose connections can cause all sorts of sound problems.
4. If you have a receiver, take a look at the equalizer settings and make any necessary adjustments.
5. Try playing around with the balance control to see if that helps improve things at all.
6. If none of these solutions work, there's a possibility that there could be something wrong with your speakers or another piece of equipment in your system. In this case, you'll likely need to get professional help in order to diagnose and fix the problem
