80mil/190mil Premium Sound Deadener

Sundown Audio Sound Deadener – Premium 80/190mil Acoustic Damping Solution Silence Isn’t Just Golden—It’s Performance. For those who demand nothing but the best, Sundown Audio delivers with its 80mil / 190mil-rated premium sound deadener —a no-compromise material designed to eliminate resonance, reduce cabin noise, and maximize audio performance. Built using the same proven composition as competition-grade dampening products, this Sundown exclusive takes it further with refined quality control, enhanced adhesion, and the trusted performance only the Sundown name can bring. Crafted for high-end builds and SPL systems where every decibel—and every detail—matters, this material combines dense, soft bitumen with a high-mass layer to stop vibration at the source. Whether you're sealing a trunk for subwoofers or lining a full competition car, this is your foundation for elite sound reproduction. Why Sundown? Because not all deadener is created equal. While others may share a similar formula, only Sundown Audio's variant undergoes enhanced QC, upgraded thermal bonding, and branding that backs performance with reputation. It’s the same concept, executed at a higher level—because that’s what the Sundown name stands for. Product Highlights: Premium 80mil / 190mil density-rated composite Industry-leading acoustic damping power 15 sheets per box (10” x 20”) – covers ~20.8 sq ft Thick 4.0mm build for maximum low-frequency absorption Weight: 34 lbs per box Self-adhesive with Sundown-reinforced backing Color: Matte Black with premium finish Installation Tips: Clean the application surface thoroughly with isopropyl alcohol or a residue-free cleaner.
