Before using the amplifier, always follow these guidelines:• Make sure the amplifier is switched off before adding or removing any connections• Keep all cables as far away as possible from the ignition cables• Always use 100% Cooper cables and good quality connectors• 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 precautionThe power rated data are based on equipment from the PRV Audio Group laboratory. Frequency reference of 1Khz with THD+N to ≤10% 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.

## Features

- COMPACT DESIGN: Digital class D Brazilian technology allows this amplifier to have a small footprint by integrating a high-speed mosfet power supply with top of line transistors to ensure performance in a small heat sink without compromising performance. Dimensions: 3.93″ depth x 5.02″ width x 2″ height
- POWER: This amplifier is designed to run your stereo system with the power it needs to perform! 500 Watts maximum dynamic RMS power output of 4x 125 Watts at 2 Ohms per channel. Its high efficiency rate of 87% provides more power with less battery consumption.
- BRIDGEABLE: Double the power output to your speakers by bridging two channels. Minimum impedance of 4 Ohms per bridged channel at output power of 2 x 225 Watts RMS
- TECHNOLOGY: A smart electronic 2-way protection circuit protects the amp if it gets too hot or if speakers fail causing a short! Focusing in sound quality, a full range response of 10 to 24,000Hz was used to give the best sound reproduction on this tiny amplifier.
- FEATURES: Heavy Duty 10 Gauge power and speaker wire Inputs. Built-in crossover filters for easy tuning! Choose between a fixed HPF at 90Hz or LPF at 90Hz + 45Hz Bass Boost or just turn it FLAT and use your external crossover or DSP settings. It also includes Variable Gain Control. Level controls are not for adjusting volume. They adjust the amount of signal that is coming into the amplifier from your signal source.
