Soundproof Jeep Wrangler – 10 Ways to Reduce Loud Noise

No matter what type of car you own, it almost goes without saying that cars make a lot of noise. However, Jeep Wranglers are especially noisy, and many people find their noise unpleasant, even though it contributes to this vehicle’s powerful image.

Fortunately, if you want to soundproof your Jeep Wrangler, all you’ll need to do is follow this guide carefully, and you should have a quieter car in no time.

How to Soundproof Jeep Wrangler

1. Insulate the Area Under the Carpet

When it comes to soundproofing your car, there are tons of options and materials available. The first thing you’ll need to do is insulate your car’s floor, beneath the carpet, and you can start this process by adding an automotive jute carpet. Due to the thickness of the carpet, it’ll provide excellent insulation and help protect your Wrangler’s flooring.

As an alternative, there are dozens of good sound-deadening mats you can use. I’ve only had experience with the self-adhesive FatMat, and I know for sure that it works extremely well. FatMat is a sound-deadener that can be used everywhere in your car, including the trunk and the engine compartment. It can also be applied to the doors and the roof.

The installation process is very easy. All you’ll need to do is remove the carpet that’s currently in your car and then put these mats on your car’s floor. After doing that, you can put the original carpet back again. Following that, you can expect to notice a big difference!

However, if you use the FatMat or the automotive jute carpet, and you don’t get the results you want, then you might consider using a car cell foam insulation deadener mat. This product has the same basic characteristics as FatMat. It’s also waterproof, so you don’t have to worry about it getting wet, and it’s extremely lightweight, along with being oil and petrol-resistant.

The installation process is quite the same: You’ll need to cut the mat with scissors or a knife to the correct size, and then install it underneath the car’s flooring. Make sure there are no gaps, because even the smallest gap can allow sound to pass through.

2. Use a Sailcloth Top

If your goal is to get rid of your vehicle’s noise completely, then this might be the right solution for you. This method is a bit more expensive than others, but it’ll be worth it in the end.

Bestop Sailcloth tops are very popular and are said to be 50 percent quieter than the regular ones. If you decide to invest in one of these, there are several different designs to choose from—at a reasonable price.

3. Buy a Sound-Deadening Headliner Kit

Another effective method you can try is a sound-deadening headliner kit. This custom-made kit will help insulate the jeep from outside noise, as well as hot and cold temperatures.

I recommend using the DE boom mat because it’s very easy to install. It’s also extremely effective and quite affordable. For the best results possible, I’d recommend pairing it with a side window trim kit, as these products work well together when fighting noise and temperature.

4. Change the Weatherstrips

One reason you might be hearing lots of wind when you’re driving quickly is the condition of your vehicle’s weatherstrips. Before taking any action, the best thing to do is check and see if the existing weatherstrips are properly sealed.

If they’re well-sealed, but you’re still hearing noise from the wind, then it’s time to replace them. You can find various weatherstrips online for an affordable price, and we recommend this one in particular. Weatherstripping is easy to install, but it’s best to let a professional do the installation, because even the smallest hole can cause a problem.

5. Change Your Tires

If your weatherstripping is fine, your existing tires could be the reason why your Jeep Wrangler is so noisy. As a result, it’s a great idea to change your tires to a less aggressive type that won’t make as much noise. Even though there’s no way to tell exactly which tires are the quietest, you may find it helpful to check out this forum thread where Jeep Wrangler owners discuss quiet tires.

6. Insulate the Area Under the Hood

It would be difficult to soundproof an engine of any kind, especially one in a Jeep Wrangler, but adding insulation under the hood can reduce the noise level dramatically. The same material used to soundproof the jeep’s floor can also be used to insulate the hood.

As complicated as it might seem, this is a rather simple process. You can start by covering the inside of the hood with self-adhesive FatMat. After you do so, you won’t be able to hear your engine’s noise, and it’s unlikely that you’ll face any difficulties while installing this material.

FatMat is the best product for the job since it can easily withstand heat, and it has a pretty long lifespan.

7. Buy Aerodynamic Mirrors

You can also install aerodynamic mirrors in your jeep, which will significantly reduce the amount of noise from wind and drafts that you can hear. These mirrors will help break down the wind’s vibrations before they can hit your side windows and make “whooshing” noises.

8. Check the Lifter For Faults

A lifter is a small, cylindrical object that’s part of a vehicle’s engine. For a pushrod engine, the lifter pushes the pushrod up into the rocker arm and opens the valve. You should take the time to check the lifter in your Jeep Wrangler, because having a faulty lifter may result in unwanted noise.

One of the most common problems is that the lifter is worn out and needs to be replaced, while another common issue is that it has accumulated dirt and debris. If you find that your lifter is the main reason behind your vehicle’s unwanted noise, you can read more about quieting a noisy lifter here.

9. Use Earplugs

Even though this method is cost-effective, you should only consider it as a permanent solution if the previous ones didn’t make a difference in your Jeep Wrangler’s noise level.

If your car continues to make a lot of noise, you can simply pop earplugs into your ears, and you won’t be able to hear anything around you. You can also use this as a temporary solution if you haven’t had time to try out all the other methods above yet.

The downside of using earplugs is that this can decrease your level of environmental awareness. If you use them on a busy road, this could actually be dangerous, as people typically rely on their hearing to keep themselves safe in heavy traffic.

With that being said, the best earplugs on the market are the Eargasm High Fidelity Earplugs. With over 2,000 positive user reviews on Amazon, these appear to be worth the price!

Conclusion

The Jeep Wrangler is noisier than most cars, because it has a very powerful engine, and the cabin is not insulated in a way that’ll completely block out noise. Luckily, there are many ways you can soundproof your Jeep Wrangler, and we’ve provided the most common solutions that won’t hamper the performance of your car. After trying these methods, you should notice a significant drop in your vehicle’s noise level, even if it still makes a bit of noise.
