Featured Build: 2014 Outback Sound Deadening

Chuck's 2014 outback

Chuck loves his Subaru, but it had some major road noise coming from the rear. After some research, he stumbled across Second Skin and never looked back. We hooked him up with the right product combination of materials to stop the road noise once and for all. Chuck chose to use the closed cell foam and the mass loaded vinyl separately to give him more flexibility to accommodate some of the parts of his vehicle that had a little less clearance. After cutting patterns to fit his exact interior, he was able to reattach panels and carpet extremely easily. With that 100% noise barrier, he ended road noise for good. Check out Chuck's weekend project where he combined OverKill Pro and Luxury Liner to create an extremely effective automotive noise barrier.

Chuck bought this 2014 Outback to enjoy the outdoors and go on road trip adventures. Unfortunately, it had a lot of drone and tire noise. After treating the floor, wheel wells, and doors with Second Skin, all that's in the past!

These inner door skins were bare bones metal. No wonder the noise came right through.

That is some clean looking mass load vinyl Luxury Liner work with closed cell foam OverKill underneath for decoupling. Now off to repeat it 3 more times...

Those rear wheel well's have absolutely nothing on them from the factory. Time to skin them with 3/8" thick OverKill Pro and 1/8" thick Luxury Liner for thermal insulation and to block out that stubborn air borne noise from the tires, exhaust, and road.

Much better...that is how you get those dB's down. Block out that road noise before it creates headaches and general irritation on those long trips.

For the trunk walls, Chuck continued on with the OverKill Pro + Luxury Liner combination, putting a stop to even the loudest air borne noises.

Chuck finished off the project by applying the closed cell foam and mass loaded vinyl combination throughout the back seat and floor of the Outback. At highway speeds, Chuck reported a drop of around 7 dB and eliminated all of the exhaust drone that was giving him headaches. Another satisfied customer! Second Skin For The Win!!!

WOW, what a difference that black on black foil makes inside of this ride...so sexy!!!

Passenger side and back seat floor all cleaned and ready.

The full cabin floor with about 35 sqft of Damplifier Pro for 100% coverage.

Rear seat area of the car stripped and cleaned with denatured alcohol.

Rear seat area looking real good and quiet. We recommend cutting out around the access ports in this area as most times they are for the fuel tank or fuel pump access points.

Left side of the trunk/hatch area on the car skinned with about 20 sqft total of Damplifier Pro in the trunk.

Right side of the trunk/hatch area of this Subaru fully skinned with Damplifier Pro. Wheel wells are very important to cover with 100% coverage even if you are only doing 40-60% coverage in other areas of the vehicle, don't skimped on the wheel wells.

Rear hatch lid covered with about 8 sqft of Damplifier Pro.

Driver's side front door skinned with 6 sqft of Damplifier Pro, making cut outs for the lock mechanisms and other items to keep them fully functional.

Passenger side front door skinned with Damplifier Pro.

And don't forget those rear doors, they need that Second Skin love too....great looking work Andrew.

Aaron's 2000 Impreza RS

Aaron's install is OG status from way back in the day when Damplifier Pro was silver. This 2000 Impreza RS has a swapped out 2003 WRX engine to give it more power. Aaron utilized 2 gallons of Spectrum in his transmission tunnel and 1 gallon on the entire trunk lid, 120 sqft of Damplifier Pro throughout with double layers in key places, and used 40 sqft of OverKill on top of the Damplifier Pro on the roof and doors along with some Speaker Tweakers to improve the door speakers. This Subaru Impreza is one quiet ride and the products have stood the test of time!!!

Aaron turned the Spectrum into Sludge and applied it to the transmission tunnel with gloved hand to kill the vibration noise and stop heat transfer through the floor.
