You like all the bumpin' bass you hear in hip hop, rap, and EDM? Well you can put that deep, pulsing bass into any kind of music — from classical, jazz, and rock to folk and Tejano — with an AudioControl Epicenter Plus bass restoration processor. Most factory radios dial down bass response to protect flimsy speakers, so when you do add a subwoofer, there's no bass to play. The Epicenter Plus will bring it back.
