Car Equalizers

An equalizer, also known as an audio signal processor, is an add-on for your car audio system. Equalizers give users the ability to fine-tune their car's sound system. An equalizer can also act as a limiter, ensuring that the spectrum of frequencies matches a user's personal preference.

What to Look For

An equalizer's ability to control sound is primarily determined on how many bands in features. Equalizaers break up the spectrum of frequencies into bands and those bands control particular frequencies that can then be adjusted accordingly.
