Description
The Dynamat Dynaplate Sound-Dampening Sheets (SKU: 13105) are engineered featuring an exotic constrained-layer dampening material specifically designed to structurally reinforce automotive body panels. Unlike traditional softer butyl mats that focus strictly on daily road-noise damping, Dynaplate is a high-rigidity structural tuning material. It is built to maximize Sound Pressure Levels (SPL) and provide maximum vibration resistance in competition car audio environments, high-output subwoofer vehicles, and critical structural sections.
Structural Reinforcement Engineering
Exotic Constrained-Layer Composition: Utilizes an advanced material composition that transforms flimsy, hollow sheet metal into a highly rigid, non-yielding surface.
SPL Maximization: By structurally locking car body panels in place, it prevents the massive mechanical air pressure generated by competition subwoofers from flexing the vehicle's metal skins, keeping the acoustic energy focused entirely inside the cabin.
Vibration Reduction & Stiffening: Delivers powerful vibration reduction across large, unsupported metal spans.
Stackable Design: These advanced sheets can be stacked in multiple layers whenever an enhanced effect or extreme structural reinforcement is required on highly problematic panels.
High-Target Application Zones
With a total kit coverage of 15.6 square feet, this three-sheet pack is perfectly sized to reinforce primary high-flex structural locations:
Woofer Enclosure Faces: Applied directly to custom subwoofer boxes or speaker baffle panels to prevent enclosure wall flexing and mechanical bass distortion.
Competition Roof Sections: Stiffens the large, thin metal span of the vehicle roof line to prevent violent overhead flexing during extreme bass notes.
Floors & Doors: Reinforces outer door skins and cabin floorboards to build an unyielding acoustic barrier against low-frequency road resonance and exhaust push.
