**Before Installing:**

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

- **Power Off**: Ensure the amplifier is switched off before adding or removing any connections to prevent potential damage.
- **Cable Management**: Keep all cables as far away as possible from ignition cables, electronic injection modules, and starter switches to avoid noise interference.
- **Quality Components**: Always use 100% copper wire and good quality connectors to guarantee reliability and performance.
- **Cable Protection**: Make sure cables do not touch sharp metal edges to prevent damage. Important: Use an 80A fuse placed 12 inches away from the battery as a safety precaution.

**Power Rating Data:**

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

**Warranty:**

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.

GENERAL SPECIFICATIONS

The power rating data is based on tests conducted by the PRV Audio Group laboratory, using a frequency range of 100Hz to 1kHz with THD+N ≤ 1% at the specified impedances. Variations in electronic components and the manufacturing process can lead to differences in measurements. This amplifier is designed for music applications with speakers, and load tests with resistive loads are not recommended.
