The invisible upgrade — quieter cabin, harder-hitting bass, zero rattles from your new system.
A brand-new sub that rattles the trunk lid instead of just hitting bass. Doors that buzz at volume even with upgraded speakers. Road noise that's just as loud after a full audio upgrade. Sound deadening is the step most DIY builds skip — and it's the difference between a system that sounds expensive and one that just sounds loud. Pro Car applies damping material to the metal beneath your panels, seals the gaps, and reinstalls everything clean.
We remove interior panels carefully, apply damping material to the metal surfaces beneath, seal air gaps, and reinstall everything cleanly.
Panels seated properly, not just clipped back on.
Doors for audio quality, floor and trunk for road noise.
Not just an audio upgrade — a comfort upgrade.
