CONTROLS AND CONNECTORS
(1) Positive Power Terminal –This is the power feed from the
positive (+) terminal of the car’s battery. Use 4-gauge cable
(MINIMUM) and good quality terminals when routing this connection.
Tighten all connections well to prevent power loss due to bad
contact. Route the power cable away from the RCA jacks and
speaker cables
1) Ground Terminal - For optimum performance, use a 4-gauge
cable MININUM! Connect this cable to your battery’s negative (-)
terminal.
Recommended Fuse –80 amps.
Remote Terminal - The amplifier will turn on when 12 volts is
applied to this terminal. This 12-volt signal is usually taken from the
Power Antenna or Remote wire coming from the source unit.
Speaker Terminals - Connect to speakers using 16-gauge wire
(minimum). Running too low of a speaker impedance will cause the
amplifier to go into a fault condition.
Crossover Filter –Linkwitz/Riley 24db slope. This control sets the
6db down point of your amplifier.
Gain –Allows input levels between 150mV (max gain) and 5 volts
(min gain) for full output.
