Product Overview

The NVX VAD8402 is an 840W RMS Full Range Class D 2-Channel amplifier built for car, marine and powersports audio systems. It delivers 300W x 2 channels at 4 ohms, 420W x 2 channels at 2 ohms and 840W x 1 channel bridged at 4 ohms with a peak power of 1680 Watts. The compact chassis measures 9.2"L x 7.2"W x 2.0"H.

Installation Requirements

Verify that your electrical system can supply 16 Volts to support the amplifier's rated output. Confirm the speaker load matches the 4-ohm, 2-ohm or bridged 4-ohm configurations listed in the specifications. Ensure the mounting location accommodates the 9.2 by 7.2 inch footprint and allows airflow around the heavy-duty aluminum alloy heat-sink.

Sustained Performance

The conformally coated marine-grade circuit board and heavy-duty aluminum alloy heat-sink are designed to maintain thermal stability during extended high-output use. Three-way protection circuitry monitors operating conditions to prevent damage from overheating, short circuits and overloads. Platinum-plated RCA inputs and screw terminals provide reliable signal and power connections over long periods.

Questions about this item

Does the NVX VAD8402 ship with the bass remote and all wiring, or must I buy a power kit separately?

The amplifier includes a bass remote giving 0 to +12 dB boost at 45 Hz, platinum-plated RCA level inputs, platinum-plated screw terminals and preamp RCA outputs for daisy-chaining; power and ground cables, fuse holder and speaker wire are not included.

Should I run the VAD8402 at 4 ohms stereo, 2 ohms stereo or 4 ohms bridged for my subwoofer setup?

At 4 ohms each channel delivers 300 W RMS, at 2 ohms each channel delivers 420 W RMS, and bridged into a single 4-ohm load the amp produces 840 W RMS; choose the wiring that matches your subwoofer impedance and desired power.

What does the 840 W RMS bridged rating mean when the amp is installed in a 16 V vehicle system?

Bridged into 4 ohms the amplifier supplies 840 W RMS continuous power; the compact 9.2"L x 7.2"W x 2.0"H chassis with a heavy-duty aluminium alloy heatsink and conformally coated marine-grade circuit board is designed to sustain that output in a 16 V electrical system.
