Sundown Audio Sound Deadening
Sundown Audio is an American car audio manufacturer specializing in high-output subwoofers and amplifiers built for serious bass enthusiasts and SPL competitors. Founded by Jacob Fuller in 2006, the company assembles products in North Carolina, USA, with meticulous attention to detail and rigorous quality testing. Their product lines—including the legendary SA, X, and Nightshade series—have earned a devoted following in the car audio community for delivering extreme power handling and deep, clean bass. Sundown was among the first to introduce high-excursion subwoofers and enhanced cooling systems, innovations that have become industry standards.
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.
