The Subaru Forester is one of the most popular SUVs on the market right now. From its great gas mileage to the high safety rating and industry-leading all-wheel-drive system, it’s easy to see why. The Subaru Forester first found its way to the USA back in 1997 and was offered with a 2.5L 4-cylinder Boxer engine, which means that the engine was essentially designed sideways. Instead of the pistons going up and down, like a normal engine, they go side to side. This engine style was really only used by two car companies, Subaru and Porsche.

Fast forward over 2 decades and the Subaru Forester is still being made and sold in the USA right now. The Forester has undergone some massive styling and technology changes over the years, but the Boxer engine still remains.

Most owners love their Subaru Forester but complain about interior noise caused by the Boxer engine, which is known to be louder than most other engines, wind noise, and road noise. Some owners have gone so far as to say that the Subaru Forester is one of the loudest cars they’ve ever owned.

But that’s why we’re here. We’re going to tell you about the best Subaru Forester sound deadening treatment so you can keep that Forester quiet and make any roadtrip a lot more comfortable.

Subaru Forester Cabin Noise Reduction Treatment

We combine two of our most popular products together in our Vehicle Soundproofing Packages. Each vehicle package includes Damplifier Pro and Luxury Liner Pro in different square footage quantities based on the type of vehicle. For a Subaru Forester we recommend our Compact Sports Utility Package to give you the most coverage and the best results.

What is Damplifier Pro?

Damplifier Pro is a carefully engineered sound deadening mat that has been a top selling sound deadening mat for the last 20 years! Have you ever heard those annoying vibrating noises when you’re driving down the road? The ones that can drive you absolutely mad if you can’t get them to stop? Well, Damplifier Pro is the solution to those annoying rattles, buzzes, and hums. These noises, known as “structural” noises, are the most common noises that drivers complain about.

When it comes to the Subaru Forester, we typically hear complaints about rattles inside the doors and vibrations caused by the Boxer engine. Damplifier Pro solves these noise problems by damping the vibrational energy that’s entering your cabin and causing the noise. As it reduces the vibrations in the metal, it dissipates that energy as a very small amount of heat (which you’ll never feel). The result is a noticeably quieter cabin. Damplifier Pro is best applied on the metal components of your Forester like inside the doors, the floor under the carpet, and against the firewall. .You only need about 60% coverage to hear a massive difference in the noise level within your Subaru Forester.

What is Luxury Liner Pro?

Now that you’ve solved the annoying structural noises in your Subaru Forester, it’s time to solve the other type of noise, airborne. Airborne noise typically comes from your tires, engine, or the road that you’re driving on. That’s why you’ll want to pair your Damplifier Pro with Luxury Liner Pro. Luxury Liner Pro acts as an extra barrier between you and the airborne noise coming up from below the vehicle. We designed Luxury Liner Pro to block as much sound as possible while fitting comfortable under your carpets, so you can sit comfortably and quietly in your Forester.

To get the best results, you’re going to want to try to achieve 100% coverage on the floor, covering the the cabin side firewall up to the dash, the floor, and and the trunk. This is because airborne noise will find its way through openings or weak points in the barrier. Think of it like a seal that’s used to keep water out of a boat. Any holes will allow water to leak in. When you combine Luxury Liner Pro with Damplifier Pro, you substantially reduce the noise level in your Subaru Forester, reducing cabin noise by 10 or more decibels.

How To Reduce Subaru Forester Tire Noise

If you do a lot of traveling, you’re going to want to check out Spectrum Liquid Deadener. This is the easiest and most cost effective sound deadening treatment on the market right now. It can be installed without having to remove a single interior panel! Spectrum, our liquid applied sound deadener can be applied by spraying it into your wheel wells with a spray gun or it can be painted on with a brush or a roller! You only need to apply 3mm of Spectrum into each wheel well for an effective treatment. Apply Spectrum in 1mm layers directly to the metal for a total of three layers. With 2 gallons of Spectrum, you can do all four wheel wells and reduce the cabin noise by 3-5 dB on the highway!
