When installing an aftermarket audio system in your vehicle, it’s easy to focus on components like speakers, amplifiers, and head units. However, one often overlooked aspect is applying Sound Deadening materials. Sound deadening plays a key role in getting the most out of any upgraded audio setup.

Applying Damping Materials

To understand how sound deadening enhances the listening experience, it helps to first explain what it is and what problems it solves. Sound deadening refers to applying damping materials to the interior metal surfaces of a vehicle. This includes the doors, roof, firewall, floor, and trunk/hatch areas.

Create an Acoustically

By applying sound deadening, it helps create an acoustically “dead” environment within the vehicle. This means only the clean audio signal from your upgraded system is heard, not ambient exterior noises. It allows you to fully appreciate the crisp highs, well-defined midrange, and deep lows your new speakers and subwoofers are capable of producing.

Tweak Factory Sound Deadening Materials

Tweak Factory offers a wide selection of high-quality sound deadening products to suit any application and budget. Here are some of their flagship materials:

Mass Loaded Vinyl (MLV)

As the most effective damping material, MLV remains the gold standard for Sound Deadening Mat. Tweak Factory’s MLV features a thick, rigid construction that provides excellent noise reduction. It can be cut to shape and holds its form well during installation.

Dynamat Extremes

For vehicle areas that experience high levels of flexing and vibration like doors, Dynamat Extremes is the top choice. Its extra-thick composition firmly adheres to uneven surfaces and strongly dampens resonant frequencies.

CLD Tiles

Constrained layer damping (CLD) tiles are specifically designed to target panel resonances. They are perfect for reducing unwanted boominess and resonance in floor pans, trunk lids, and most effectively, doors. Tweak Factory’s CLD tiles deliver a smoother, clearer sound.

Foam Products

For situations where weight is a primary concern, Tweak Factory’s closed-cell polyurethane and vinyl foam pads can provide vibration-damping benefits while keeping weight gains minimal.

Sound Deadening Kits

Tweak Factory also offers Sound Deadening Van Kits pre-packaged with all the materials needed for a full vehicle application. Different kits exist for cars, trucks, SUVs, and other vehicle types.

Pro Kit

The Pro Kit is tailored for sedans and coupes. In the kit you’ll find MLV, CLD tiles, polyester tape, and foam pads sufficient to cover all door panels, the rear deck/shelf area, and the trunk. Proper application of these included materials sees drastic road noise reduction and clearer soundstage imaging.

Truck Kit

For trucks, vans, and larger vehicles, the Truck Kit includes expanded quantities of materials. In addition to doors, it features enough MLV and foam to treat the roofline, firewall, and entire floorplan area as well. The extra coverage creates a highly insulated acoustic chamber with powerful damping.

SUV Kit

Rounding out their lineup is the SUV Kit. As SUV cabins tend to be quite large, this kit packs even more products. It supplies all necessary materials to soundproof doors, the roof, the cargo area, the rear shelf, and wheel wells for a comprehensive SUV sound deadening job. The wheel well treatment alone cuts major frequencies of boom and rattle.
