Summary

SAFETY PRECAUTIONS

Fuse amplifiers power wire at the battery

Fuse the power wire within 12 inches of the car's battery to protect the battery from short circuits.

Make all ground wires as short as possible and at the same point

Keep ground wires short and connect all units to the same ground point to reduce ground loops.

POWER CONNECTIONS

Connect the amplifier to the cars battery

Use 4-8 gauge wire for power connection. Fuse the wire within 12" of the battery for protection.

Connect the ground terminal of the amplifier to the cars chassis

Use a short 4-8 gauge ground wire connected to a clean, paint-free chassis point.

Connect the remote terminal of the amplifier to a switchable +12 V source

Connect to the radio's remote output or power antenna wire to turn the amplifier on/off with the head unit.

SIGNAL CONNECTIONS

SPEAKER CONNECTIONS

TWO CHANNEL SPEAKER CONNECTIONS

Connect speakers to the L+/- and R+/- terminals. Ensure proper phasing (+ to +, - to -).

FOUR CHANNEL SPEAKER CONNECTIONS

Connect front L/R and rear L/R speakers to their respective terminals, ensuring correct phasing.

SPEAKER CONNECTIONS (BRIDGED)

TWO CHANNEL BRIDGED SPEAKER CONNECTIONS

Bridge the amplifier for mono output by connecting a single speaker to the bridged terminals (4 Ohm min).

FOUR CHANNEL BRIDGED SPEAKER CONNECTIONS

Bridge channels for mono output to drive subwoofers or center channels (4 Ohm min per bridged pair).

ADJUSTING THE X-OVER AND BASS

TROUBLE SHOOTING THE SYSTEM

Protection L.E.D. Illuminated

Check for speaker shorts, grounding issues, impedance too low, or overheating; fix and reset.
