This installation guide offers examples of crossover and equalizer (EQ) installation types and suggested system layouts. The installation of your crossover or EQ will depend on the make and body style of your vehicle as well as the equipment purchased.

Tools needed, depending on vehicle

A note about wiring: In addition to the tools listed above, your EQ or active crossover installation will require power and ground wiring, plus RCA cables, terminals, and a remote turn-on lead. The easiest way to get all of these items is in an amplifier wiring kit, available at crutchfield.com.
