Before Installing:

You must follow the instructions for the product’s installation to guarantee optimal performance. If you have any questions, get in touch with us. Before using the amplifier, always follow these guidelines:

• Make sure the amplifier is switched off before adding or removing any connections. This prevents possible damage to equipment.

• Keep all cables as far away as possible from the ignition cables, electronic injection modules and starter switch since they may cause noise interference;

• Always use 100% Copper wire and good quality connectors. This guarantees reliability and performance.

• To avoid damaging the cables, make sure that they do not touch sharp metal edges. Important: For this amp use a 25A fuse 12 inches away from the battery as a safety precaution

The power rating data is based on equipment from the PRV Audio Group laboratory. Rated power tested with 100Hz to 1KHz sinusoidal signal and THD <= 1%, with resistant load referring to the indicated measurements. 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.

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.
