Silence Your Subaru: A DIY Guide to Lowering the Horn Noise on Your Outback

Are you frustrated with the loud and obnoxious horn of your Subaru Outback? Do you want to lower the volume of the horn but don’t know where to begin? Look no further! In this guide, we’ll show you various methods for lowering the horn sound on your Subaru Outback.

Replacing the Horn

One option for lowering the horn sound on your Subaru Outback is to replace the horn with a quieter version. This can be done easily by purchasing a new horn and installing it yourself or having a mechanic do it for you. Quieter horns can be found from a variety of manufacturers, and you can choose one with a lower decibel rating to suit your preferences.

Installing a Resistor

Another option is to install a resistor, which will limit the amount of power that goes to the horn, thus reducing its volume. This can be done using a simple electronic circuit that can be purchased online or at a local electronics store. Installing a resistor in the horn circuit is a bit more complicated than replacing the horn, and requires some basic knowledge of electronics and wiring.

Using Sound-Deadening Material

If you’re looking for a more comprehensive solution, you can use sound-deadening material such as dynamat to reduce the amount of noise that enters the car. Applying this material to the doors, roof, and trunk can help significantly reduce the overall noise level. While this method is more involved and time-consuming than the previous two, it can be a great way to soundproof your car.

Safety Concerns

When modifying any part of your car, it’s important to consider safety concerns. Modifying the horn could impact your car’s ability to alert other drivers in emergency situations. Always test your new horn to ensure it’s loud enough to be heard by other drivers on the road.


Q: Can I simply disconnect the horn to make it quieter?

Q: Will modifying the horn void my warranty?

A: It’s best to check with your dealership to understand the terms of your warranty. Modifying the horn could potentially void the warranty, so proceed with caution.

Q: Which method is the most effective?
