Installation

Select proper location and prepare wiring connections.

Choose installation location: Well-ventilated area, secure mounting surface.
Connect power wires: Run +12V wire from battery with inline fuse, ground to chassis.
Connect audio inputs: Use RCA cables from head unit or speaker level inputs.
Connect speakers: Properly wire speakers observing polarity.
Connect remote turn-on: Wire to head unit remote output.

WARNING! Disconnect battery before installation. Ensure proper fuse rating. Avoid power wires near audio cables.

First-Time Setup

Configure amplifier settings after installation.

Set gain control: Start at minimum, adjust while playing music at 3/4 volume.
Adjust bass boost: Set to desired level (recommend moderate settings).
Configure crossover: Select high-pass or low-pass as needed for speakers.
Set crossover frequency: Adjust according to speaker specifications.
Test operation: Verify all channels working properly.

CAUTION! Do not set gain too high to avoid distortion. Ensure proper ventilation around amplifier.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power	Power connections/fuse	Check +12V and ground connections; verify fuse; check remote wire.
Protection mode active	Overheating/short circuit	Allow to cool; check speaker wires for shorts; verify impedance.
No sound	Input connections/settings	Check RCA/speaker level inputs; verify gain setting; check source unit.
Distorted sound	Gain setting/clipping	Reduce gain control; check input level; verify power supply.
Amplifier overheats	Ventilation/load	Improve ventilation; check impedance load; reduce gain settings.

Reset: Disconnect power for 30 seconds to reset protection circuits.
