GETTING STARTED Mounting Wiring • Mount the amplifier on a flat, secure surface. • Investigate the layout of your automobile thoroughly before drilling. • Place the amplifier in a location that allows air to circulate around it to keep it cool. • If possible, mount the amplifier vertically for proper heat dissipation. • Avoid mounting the amplifier upside-down as this will not provide adequate ventilation for the amplifier.
INSTALLATION POWER CONNECTIONS Make sure to mount the amplifier in a location where there is enough room to have access to the knobs and terminals. 2 1 Make sure to disconnect the negative (-) battery terminal before routing cables and wires to prevent electrical shorts. Power Capacitor Mark the mounting screw holes to be drilled with a marker. Drill the holes on the marked spots with an electric drill.

POWER CONNECTIONS Continued... The remote wire, when connected to the amplifier, is designed to turn on the amplifier automatically when your stereo is turned on. REMOTE For a good electrical connection and maximum power transfer, use the same gauge size ground cable as the power cable. The length of the cable should be as short as possible and as close to the amplifier as possible. GROUND 1. Locate the remote wire on the stereo head unit. 2.
AUDIO INPUT LINE OUTPUT The audio inputs on the side panel of the amplifier receive low level signals from the RCA outputs of the stereo head unit. If your stereo head unit does not have RCA outputs, a High-to-Low level converter (not included) must be used. Both line inputs need to be connected to the stereo head unit in order to use all of the speaker outputs.
REMOTE CONNECTION The remote control knob will allow you to control the bass output from your dashboard. SPEAKER WIRING Single Subwoofer Wiring Remote Cable Plugin Remote Plug on Amplifier 2Ω - 4Ω SPEAKER IMPEDANCE Connect the subwoofer’s positive + terminal to the positive + terminal on the amplifier, then connect the negative (-) terminal of the subwoofer to the negative (-) terminal on the amplifier.
