Project Summary
Transformed a noisy 2022 Subaru WRX cabin into a quiet listening room using a full SoundSkins Pro acoustic dampening package combined with Hertz component speaker upgrades.
1. The Vehicle & OEM Challenge
Subaru WRX cabins are notorious for high road roar, exhaust drone, and thin door panel vibrations that ruin speaker sound quality at highway speeds.
2. Custom Engineering & System Design
Audio Matrix completely stripped the interior interior carpet, door panels, and trunk liner to apply 100% coverage of SoundSkins Pro 3-in-1 butyl, aluminum, and acoustic foam dampening sheets.
3. Step-by-Step Technical Installation Breakdown
1. Interior Teardown & Surface Preparation
We removed seats, carpeting, and door cards, cleaning bare metal floorboards with degreaser to ensure maximum material adhesion.
2. Multi-Layer SoundSkins Application
Rolled out SoundSkins Pro dampening sheets across doors, transmission tunnel, rear wheel wells, and trunk floor, eliminating sheet metal resonance.
4. Real-Time Calibration & Post-Installation Results
Cabin ambient noise dropped by 5.8 dB at 70 MPH. Door closure sounds solid like a German luxury sedan, and Hertz component speakers deliver rich, detailed sound.

Installation FAQs for This Project
How much weight does full cabin sound deadening add to a car?
A full cabin treatment adds approximately 25-35 lbs of material weight — virtually unnoticeable in vehicle handling while dramatically improving daily driving comfort.
