Tune your car stereo system to suit your needs or correct your vehicles natural acoustic problems with an equalizer also known as an EQ. Adjust individual bands or range of bands with a parametric equalizer and tailor your systems frequency response to your ears.

Equalizers are multi-channel sound enhancement devices, designed to input sound outputted from audio sources such as receivers; and seamlessly filter/bypass and send (return) that audio source (output) to the same or other audio peripherals.
