stands for "Easy Equalizer." This was Pioneer’s proprietary branding for their built-in sound customization suite.

Furthermore, the manual is a historical document of the car itself. In 1982, the automobile was the last bastion of unregulated personal space. The EQ-45WX4 turned a Datsun or a Volkswagen Rabbit into a mobile listening room. The manual’s section on “Noise Suppression” is particularly telling. It instructs the user to install capacitors on the alternator and to ground the chassis to prevent "whining" that changes pitch with the engine RPM. This is not an instruction manual; it is a battle plan against the hostile environment of the internal combustion engine. The text acknowledges that the car is a terrible place for high fidelity—vibrations, electrical interference, road noise—and yet, it insists that fidelity is worth fighting for.
