This issue is extremely common, especially in factory systems. Many modern vehicles use bass roll-off or loudness compensation to protect factory speakers. As volume increases, the system intentionally reduces low frequencies, making bass seem to disappear.Before changing components:
– Check EQ, bass enhancement and loudness settings
– Ensure no speed-sensitive volume or dynamic EQ features are enabled
If the issue persists:
– Factory systems often require upgraded speakers and amplification
– Aftermarket systems may simply need re-tuning or DSP adjustment
An Authorised Focal Dealer can quickly diagnose whether the issue is tuning-related or hardware-related and recommend the correct solution.
