**Before Installing:**

To ensure optimal performance, carefully follow the product’s installation instructions. If you have any questions, please contact us. Always adhere to these guidelines before using the amplifier:

- Ensure the amplifier is switched off before adding or removing any connections to prevent possible damage to equipment.
- Keep all cables as far away as possible from ignition cables, electronic injection modules, and starter switches to avoid noise interference.
- Always use 100% copper wire and high-quality connectors to ensure reliability and performance.
- Make sure cables do not touch sharp metal edges to avoid damage. Important: Use a 25A fuse 12 inches from the battery as a safety precaution.

The power rating data is based on tests conducted in the PRV Audio Group laboratory. Rated power is tested with a 100Hz to 1KHz sinusoidal signal and THD <= 1%, with a resistive load corresponding to the indicated measurements. Note that electronic components and the manufacturing process can cause variations, leading to measurement discrepancies. This amplifier is designed for music applications (with speakers); resistive load tests are not recommended.

PRV Audio products are guaranteed against any manufacturer’s defects in material and workmanship under normal use for ONE (1) YEAR from the original purchase date.

GENERAL SPECIFICATIONS

The power rating data are based on tests conducted with equipment from the PRV Audio Group laboratory. Measurements are taken with a frequency reference of 100Hz to 1kHz and THD+N ≤ 1% at the specified impedances. Due to potential variations in electronic components and the manufacturing process, there may be slight discrepancies in these measurements. This amplifier is designed for optimal performance in music applications (with speakers), and load tests with resistive loads are not recommended.
