Silence the Rattle: Soundproofing Tips for Subwoofer Boxes That Hit Harder | #subwoofer boxes
Rear parcel shelves can resonate under continuous bass pressure, especially when subwoofers are installed in the trunk. SoundSkins Global Foam is designed to absorb airborne vibration that builds up beneath this panel during playback. Installing Foam under the parcel shelf helps reduce sound reflections that may travel back toward the cabin, interfering with midrange clarity. This treatment limits panel movement that can introduce rattling at moderate volume levels. By controlling resonance in this wide interior surface, SoundSkins Foam supports smoother frequency response and improves how low-end energy is perceived from the front seating position without requiring additional enclosure adjustments.
