A car stereo that whines, buzzes, and pops as you’re driving down the road can ruin the time you spend in your car. You may end up turning your stereo off.
If you have a long commute, a car ride in silence will probably feel a lot longer than it is. A noise filter can bring back your tunes without the interference that makes listening to your stereo painful.
Don’t be intimidated if you don’t know how to install a noise filter on car stereo systems. Noise filter installation is easier than you probably think, and we’ve compiled a guide on installing it here.
Installing a Noise Filter in your Car’s Stereo System
A noise filter for a car stereo is a ground loop isolator. This small and inexpensive device interrupts the constant ground loop noise within the wiring of a car. A noise filter interrupts and absorbs that sound before it comes through the speakers and ruins the stereo’s sound.
When installing a noise filter, you’ll want first to know what type it is. There are two main types of noise filters:
- An inline noise filter is installed directly into the wiring of the car. This simple device is a core of magnetic ferrite with the audio power wire wrapped around it. The ferrite pulls the noise interference caused by the car’s electrical system from that wire and absorbs it so that the sounds don’t reach the car speakers.
- An RCA line filter is plug-and-play and requires no wiring knowledge. This filter is a more accessible filter to install.
Below, we’ll go into choosing the right filter for your car stereo and then installing it depending on the type.
