Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 in the contiguous US. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

Sundown Audio’s premium sound deadener is built to eliminate resonance, reduce cabin noise, and maximize audio performance. It combines dense bitumen with a high-mass layer to stop vibration at the source, making it a strong foundation for subwoofer trunks and full competition builds. Each box contains 15 self-adhesive sheets (10″ x 20″) covering roughly 20.8 sq ft, with a 4.0mm thickness for maximum low-frequency absorption. For best results, clean the surface with isopropyl alcohol, warm the material with a heat gun for flexibility, and press firmly over contours for full contact.
