NXR Amplifiers

Multi-Channel Flexibility

The 4 channel models feature flexible 4/3/2 channel operation complimented with dual independent crossover networks and bass boost for the front and rear channels. Additionally the NXR300.4 and 400.4 offer two or four channel input configurations. This gives the flexibility of using only two channels of signal input when needed. The four channel input configuration offers normal independent operation allowing for front and rear fading capability through the head unit.

Class D Design

The NXR400.4, 500.1 and 1000.1 amplifiers feature High Efficiency Class D operation providing long term operation without thermal shutdown and  less stress on the car's battery.
