One of the most overlooked components is the car’s electrical system. The stereo’s amplifier has to drive the speakers with enough power to make music sound like the artist intended. But the sound also needs to come from all of the speakers working together, with each one reproducing different frequencies to create an immersive soundscape.
To achieve this, the stereo needs to have a strong connection to the speakers, and the sound has to travel through the car’s body without being muddled or lost. That’s where a ground loop isolator comes into play.
Read on to learn more about what a ground loop isolator is and how to choose the one that’s right for you.
