Before connecting your amplifier review all recommendation. Any connection to the amplifier input or output must be performed only when amplifier is OFF.
The gauge of the power supply wiring is extremely important to reach the desired amplifier output and for the amplifier’s safety. Not using the recommended wire gauge will result in power loss and overheating
of cables. It is important that the power supply cables are the shortest possible length, maximum recommended length is 10 feet. Always use 100% Cooper cables and good quality connectors. This guarantees
the sound’s quality and fidelity; To avoid damaging the cables, make sure that they do not touch sharp metal edges. Important: Use a fuse 12 inches away from the battery as a safety precaution.
In order to avoid interferences, the signal cables ( RCA) must be kept away from the original wiring of vehicle and from any other power supply cable.
Amplifier must be installed in a solid and ventilated area. Do not mount amplifier to the back of a subwoofer box; excess vibration may cause damage to the amplifier.
The power rated data are based on equipment from the PRV Audio Group laboratory.
Frequency reference of 100Hz to 1kHz with THD+N to ≤1 % in impedances referring to the indicated in each measurement. The electronic components and the
manufacturing process can present manufacturing variations, thus leading to a variation in the measurements made. This amplifier is designed to perform on music
applications ( with speakers ), any load test ( resistant load ) is not recommended.

Variable High Pass Filter at 12dB/Oct slope allows adjustment from:
MDX1800.1 - 10Hz to 120Hz MDX2500.1 - 10Hz to 160Hz
It determines the beginning of the amplifier operating frequency. Allows the elimination of low
frequency sounds, delivering the right frequency range to avoid damage to the components.
Variable Low Pass Filter allows adjustment from 50Hz to 1,000Hz at 12dB/Oct Slope, when
switch is Turn On. When switch is turn Of f amplifier will be at full range up to 25,000Hz.
It determines the end of the amplifier operating frequency. This ensures that only the lowest
frequencies are reproduced by the amplifier.

LED Indicator
CLIPPING YELLOW LED Occasionally with Strong Music Notes
- Indicates when amplifier output begins to distort the sound.
The clipping LED is a tool to diagnose when you have reached the limit of the amplifier output.
It will blink if you have exceeded the max output power on the true working impedance of the
amplifier or due to the lack of battery power in the system.
-Amplifier must not operate with excessive flashing of the clipping LED.
Abuse may cause damage to amplifier or speakers.
- If Audio CUT-OFF and the YELLOW LED is “FLASHING” this indicates a protection system
against Short-circuit or impedance lower than supported by the output.
ON BLUE LED
- When LED is “ON”indicates amplifier is ON, ready to operate.
- When LED is “FLASHING” indicates Low/High battery voltage
protection. Amplifier must operates between 9 to 16 volts.
- When LED is “ON”indicates High Temperature Protection for excessive temperature. Audio
stops and the fans run at maximum speed to cool internal components.
- When LED is “FLASHING” indicates Damage Amplifier Protection.
This means the amplifier has some damage, can no longer operate, and must be sent to one
of our technical repair centers for review.
