Before connecting your amplifier review all recommendations, 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;
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.

ON BLUE LED
-Indicates amplifier is ON, ready to operate..
PROTECTION RED LED
- Indicates when the amplifier is in protection mode. This means the
amplifier has some damage, can no longer operate, and must be sent to
one of our technical repair centers for review.
Never use speakers with impedance under the nominal impedance of the amplifier.
Warranty will be voided if ran below their rated ohm load.
HPF / Subsonic
LPF
High Pass FilterFixed at 90Hz at 12dB/Oct slope, used for speakers, tweeters
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.
Low Pass FilterFixed at 90Hz at 12dB/Oct Slope + 14dB boost at 45Hz, used only for bass signal
It determinesthe end of the amplifier operating frequency.
This ensures that only the lowest frequencies are reproduced by the amplifier.

PRV Audio products are guaranteed for a period of ONE (1) YEAR from the date of original
purchase against any manufacturer's defects in material and workmanship under normal use.
This warranty does not extend to damage resulting from, but not limited to:
Improper installation, product modification, misuse and neglect, abuse (items returned repeatedly for the same damage may be
considered abuse), damage resulting from attempted repairs by unauthorized repair centers or individuals, damage incurred during
shipment, blown outputs or power supplies in amplifiers from overdriving or under voltage due to ignoring the LED Clipping Indicator,
excessive vibration damage in amplifiers due to improper installation, using an aluminum wire and/or any other wire that is not
recommended in the owner’s manual on a high-current amplifier, installation and removal costs of the products associated with obtaining
a warranty claim, product damaged in an accident, damages due to criminal activity, by ‘acts of God’ (lightning, flooding, etc.), products
with the serial number and/or warranty seal removed or damaged.

NO SOUND
POOR BASS RESPONSE
GROUND NOISE
- Check first for: blown fuses, poor or incorrect wiring connections, incorrect crossover
setting, switch on & off and gain controls, etc. If protection is present in the system, the
amplifier protection mode will go on - Follow LED indicator Instructions .
- Chec if RCA cables are properly connected and check if speakers are working.
- Check if LEVEL knob on the amplifier is set to MIN.
- It is caused by speaker out of phase (reverse polarity). Check if speaker wires (+) & (-) are
- It is caused by poor grounding of either the PRV amplifiers, other amplifiers in the system,
head unit, battery, alternator, or other components in the system.
- PRV amplifiers are engineered to be fully compatible with all manufacturers’ head units.
Some head units may require additional grounding to prevent noise from entering the audio
signal, If this occurs then we recommend to repair or replace the head unit.
- In order to avoid additional ground noise: loop the ground wires and avoid using DO NOT
several ground wires from different points. Remove paint/rust from chassis, secure tight
