Service manual above
If your Sony LBT-SH2000 audio system is cutting out when you increase the volume or when you put on the "Z Groove" feature, it could be an issue with the speakers, the audio cables, or the system's internal components. Here are a few things you can try to troubleshoot the issue:
- Check the speaker connections: Make sure that all the speaker wires are properly connected to the audio system and the speakers themselves. If any wires are loose or disconnected, it can cause audio dropouts.
- Check the audio cables: If you're using audio cables to connect external devices to the audio system, make sure they are securely connected and not damaged. Damaged or loose audio cables can cause audio dropouts and other audio issues.
- Check the system's internal components: If the speaker connections and audio cables are not the issue, it could be a problem with the audio system's internal components. In this case, it may be best to have the audio system professionally serviced or repaired.
- Try resetting the audio system: Turn off the audio system and unplug it from the power outlet for a few minutes. Then, plug it back in and turn it on. This can sometimes help resolve software or firmware issues that may be causing audio problems.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.

The Alternator may not be providing sufficient charge to the battery. As the volume level increases, the drain on the speakers also increases and this cause more charge to be drawn eventually causes the speakers or stereo to be cutoff due to lack of power.
I hope this is helpful? PLEASE "ACCEPT" and mark it "HELPFUL" to complement my little effort. Hope to bring you more detailed answers.
