Installation - General WARNING! Before driving the amplifier mounting screws through any surface, be sure of what is behind that surface. Check for the gas tank, brake lines, and any vehicle wiring harness. Never run wires outside or under the vehicle or where they could become broken or interfere with the safe operation of the vehicle. Before You Install Before you install the unit, disconnect the negative (–) battery cable in the engine compartment of the vehicle. Doing so will prevent damage

Installation - Wiring Installation - Wiring Amplifier Fuses Although the amplifier has an internal fuse, additional fuse protection should be installed as close as possible to the battery on the positive (+) power wire going to the amplifier. An inline fuse should be installed at no more than 18" (46cm) on the positive (+) power wire. The rating of the inline fuse should equal the value of the internal fuse of the amplifier if only the single amplifier is connected to this wire. If other devices

Tuning The Amplifier - Front or Rear Speakers 1) Music The material chosen for head unit/amplifier system setup must be both clear in recording quality and dynamic in amplitude. Many audiophile “test” discs have musical tracks with both of these characteristics and should be used. 2) Input Sensitivity Control Turn control all the way counterclockwise (minimum position). In this position, the amplifier will be less sensitive to the input signal from the head unit (refer to the diagram on page 5)

Tuning - Front / Rear Speakers Tuning The Amplifier - Front or Rear Speakers 6) Input Sensitivity Control Slowly rotate the control clockwise (refer to the diagram on page 5) until maximum undistorted playing level is heard from the speakers. Listen closely for bottoming from the speakers. If detected, rotate the input sensitivity control counterclockwise until it is eliminated. 7) Crossover Controls To achieve higher undistorted playing levels from the main speakers, the highpass crossover mu

Tuning The Amplifier - Subwoofer (s) 1) Input Switch Move switch to the right-hand (MONO) position (refer to the diagram on page 5); the inputs are summed to mono. Connect the subwoofer to the speaker output terminals marked for mono operation. NOTE: Subwoofer impedance is 2 ohms minimum. 2) Head Unit The head unit should have all controls such as bass, treble, balance, and fader set to the flat or centered position. The volume control should be at the minimum setting. If the head unit has any

Tuning - Subwoofers Tuning The Amplifier - Subwoofer (s) 5) Lowpass Crossover Control Move the selector switch to “ON” (refer to the diagram on page 5). In this setting, lowpass signal is sent to the speaker outputs. Experiment with the crossover point settings while the subwoofer is active. A higher setting will increase the perceived output, and a lower setting will make the bass response more omnidirectional. 12 or 24dB crossover slopes are available. Depending on your installation and listen
