seTuP PrOcedure GTO series amplifiers include a setup CD with test signals that makes it easy to precisely set the amplifier’s input gain to maximize the amplifier’s signal-to-noise and dynamic range performance with your vehicle’s audio system. The amplifiers feature three Gain Indicator LEDs that provide all the feedback you need to quickly set the gain to the proper level. - Page 9 1. Initially set all amplifier Input Level switches to the “Hi1” position. nOte: If you have connected the GTO-5EZ or GTO-3EZ amplifier to your factory audio system’s speaker outputs, the audio system may show a “speaker disconnected” message, or may fail to play with an amplifier connected to its output.
