How Much Does it Cost to Soundproof a Car?
Author: Eric Zuck
The cost to soundproof a car depends on a handful of factors. Are you doing the install yourself, or are you outsourcing to an installer? We'll go through the cost of soundproofing a car the right way and connect you with an installer if you need one. Let's start with three important questions:
What Type of Car Are You Soundproofing?
Do you have a 2 Door Coupe or a Full Size SUV.A larger vehicle takes more material.
How Loud is the Car and How Much Sound Do You Want to Reduce?
If you’re experiencing 75-85 db driving at highway speeds, that's too loud. It's worth it to make a larger investment to address both structural and airborne noise.
What are the Sources of Noise in the Car?
As you drive your vehicle, it generates some combination of road noise, tire noise, engine noise, and wind noise. Diesel engines tend to be louder, and boxier cars tend to have more wind noise. Off-road tires and performance tires can also generate a lot of extra noise. There may also be rattling plastic panels or roof flex from a sub in the trunk. We have solutions for each. We cover the different car soundproofing treatment strategies in our guide, but give us a call at 800-679-8511 to discuss it with one of our professionals.
Cost of Soundproofing a Car, Truck, Suv, or Van
As we mentioned, there are two types of noise in a vehicle: structural noise and airborne noise. A good car soundproofing plan accounts for both:
- Structural noise is the vibrating metal components. You need sound deadening materials designed to stop vibrations. We have two go-to products to damp those vibrations: Damplifier Pro peel & stick sound deadening mats or Spectrum liquid deadener. Both score extremely well in NVH testing and are absolutely necessary. Apply them to as much metal as you are able. Stop the vibrations, stop the noise. We also recommend staying away from cheap alternatives like peel and seal sound deadening mats.
- Airborne noise is the road, engine, exhaust, and loud tire noise that you need to quiet down. To stop airborne noise, you have to block it with an automotive sound barrier. Luxury Liner Pro is designed to be incredible at blocking noise, and would be installed with 100% coverage on the cabin side firewall, floor, and trunk.
You can get material to treat them individually, or you can get the Second Skin Vehicle Soundproofing Kits for a bundle and save discount on the best car soundproofing. We developed the Second Skin System to help customers maximize their car soundproofing. If you combine sound deadening with a premium noise barrier in a vehicle, you’ll reduce the noise level when traveling at highway speeds by 10-15 db.

Cost of Soundproofing Different Parts of a Car
Using a targeted approach for specific noise issues is a great way to get the best bang for your buck. If you just want to focus on soundproofing one or two parts of your vehicle, we have kits for each part that have everything you need in them, including accessories like tape, spray adhesive, and a hand roller. We also have kits with insulation like sound deadening foam combined with Damplifier Pro in the doors, on the roof, behind plastic panels, and under the hood.
