Stable into 2 ohm stereo or 4 ohm mono loads.
Protects amplifier from accidents and undesired operation.
Variable bass boost circuit which provides up to 12 dB of boost at 40 Hz.
12 dB High pass or Low pass fixed at 80Hz. Defeatable for full range operation.
Ensure structural soundness and adequate ventilation for the amplifier.
Use the supplied 3mm allen wrench to access mounting holes and wiring connections.
Drill 4 holes using a 7/64″ drill bit and use the supplied #8 screws.
Use low level RCA or high level speaker connections. RCA is preferred.
Disconnect battery before working with power connections.
Connect to a short, paint/corrosion-free metal chassis area.
Install fuse near battery and select correct wire gauge for amplifier.
Use with High Level inputs for fader to work. Do not use shorting plugs.
Amplifier operates into a minimum impedance of 2 ohms per channel in stereo.
Operates into a minimum impedance of 4 ohms in bridged mono operation.
Operates into 2 ohms stereo and 4 ohms bridged operation.
Set crossover at 80Hz (high/low pass) or OFF for full range. Never change with system on.
Match head unit output to amplifier input. Adjust slowly until distortion, then back off.
Boosts output at 40 Hz. Adjust gain after boosting to avoid clipping.
Power output ratings under various impedance, voltage, and THD conditions.
Includes dimensions, frequency response, input sensitivity, and S/N ratio.
Green LED (on/ready), Red LED (protection engaged).
Covers no output with green LED off, green on, or red on.
Check balance, connections, and swap cables/speakers to isolate the issue.
Whining sound varies with RPM. Check RCA cable, routing, ground, and gain.
Check system phasing, balance control, and speaker wiring polarity.
Ensure correct jumper cable connections to avoid fuse damage or system failure.
Details 3-month (retail) or 2-year (dealer install) warranty against defects.
Return defective merchandise to dealer with RMA number and proof of purchase.
Excludes damage from improper installation, misuse, water, or unauthorized repair.
