Boss Audio's newly designed Onyx line car amplifiers brings you every configuration you could need for any setup that you want. The new NX3000.4 model is a 4-Channel MOSFET amp with 1500W x 2 Peak Power (Bridged). With new state of the art circuitry and power supply design optimize efficiency while delivering tremendous power output with plenty of headroom.

Four-Channel or Bridged Mode:
Run in 4-channel mode for 750 Watts x 4 peak power at 2 ohms (300 Watts x 4 at 4 ohms) or bridge at 4 ohms for 1500 Watts x 2 peak.
Trimode Operation:
This allows you to send your signal to a tri-way crossover for adding a subwoofer to the front/rear two-channel output.
Remote Subwoofer Level Control:
Onyx amps include a remote subwoofer level control. If you're using it to power a sub, you'll be able to quickly make level adjustments.
Line/Speaker Level Inputs:
Separate line and speaker level inputs mean the Onyx can handle high-level signals from receivers lacking RCA outputs.
Built-In Crossovers:
This amplifier features variable high and low-pass crossovers, so you can adjust the sound to suit whatever speakers you're driving.
Variable Gain Controls:
Allows you to match the input gain to your receiver for better sound with less distortion.
MOSFET Power Supply:
For high performance with low heat.
Bass Boost:
Add a little extra low-end power with 0 to +18dB of variable bass boost.
Power and Protection LEDs:
Protection LEDs let you know when there's a problem.
