Input Impedance: Low-Level 10K Ohms High-Level 100 Ohms Input Sensitivity: Low-Level 200 mV - 8 V. High-Level 2V - 10 V Filter type: Selectable Full/Low-pass Crossover @ 12dB/Octave Filter Crossover: LPF 50-250 Hz (variable) Supply Voltage: 12 volts, negative ground Fuse Rating: 30 amps.
1. Although this unit is designed with built-in self-protection circuits, there may be a possibility of damage if it is not wired correctly. Please follow the wiring instructions carefully for the type of system being used. 2. The last lead to be connected is the wire to the positive( ) terminal of the battery.
1. Select a mounting area where the amplifier will have sufficient air circulation for proper cooling. Inadequate air circulation will cause the temperature of the amplifier to rise and will trigger the thermal protection mode.
The wiring of your amplifier will depend on the system and speakers you are using but will either be a stereo, mono, or mixed-mono application. The following pages illustrate the input and output wiring for these types. please refer to the appropriate diagrams for the system configuration you are using.
4. Speaker Connections Depending on the type and number of speakers used with the amplifier , wire them to the speaker terminals as per the appropriate wiring diagram. For most applications, #16 gauge wire should be used for the speaker leads but in no case thinner than #18 gauge.

-14- Power Indicator Lamps After initial set-up, the amplifier should not require any further adjustment unless there is a change in the car stereo or speaker system with which it is used. If activated by a rise in emperature, the unit will resume operation after cooling of f to a normal operating range.
LPF Crossover Frequency Control This Control selects the crossover frequency when the Sub woofer Crossover Selector is in the "LPF" setting. Adjust it to the appropriate position for the characteristics and crossover frequency requirements of the speaker system with which the amplifier is being used.
