Description

Boss Audio's newly designed Onyx amplifiers bring you every configuration you could need, for any system setup. State-of-the-art circuitry and power supply design optimize efficiency while delivering tremendous power output with plenty of headroom. The NX2500.4 is a four-channel MOSFET amp with 1250 watts x 2 peak power (bridged).

Four-Channel or Bridged Mode
Run in four-channel mode for 625 Watts x 4 peak power at 2 ohms (250 Watts x 4 at 4 ohms) or bridge at 4 ohms for 1250 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.
