Why drivers upgrade
Your factory system has no low end. This fixes that.
Factory amplifiers run out of power exactly where bass lives. The NX600.1 gives your subwoofer clean, controlled power without touching the rest of your system.
Tuned for your sub, not just loud
A 10 to 50 Hz subsonic filter protects the woofer, a 50 to 250 Hz low pass keeps it on bass duty, and 0 to 18 dB of boost at 40 Hz dials in the feel.
Fits where nothing else does
3.5 by 1.6 by 5.8 inches. Under a seat, behind a panel, or beside the sub box, with high-level inputs and auto turn-on for a clean factory install.
Built for bass
Everything a subwoofer install needs, in a chassis the size of a paperback.
600W Class D Monoblock
250W at 4 ohm, 400W at 2 ohm, 600W at 1 ohm. High efficiency, cool running.
Subsonic and Low Pass Filters
10 to 50 Hz subsonic, 50 to 250 Hz low pass, so the woofer plays only what it should.
18 dB Bass Boost
Adjustable 0 to 18 dB at 40 Hz for the exact amount of punch you want.
Remote Bass Control
Add the DRC1 knob to adjust sub level from the driver's seat.
EPS High-Level Inputs
Type D inputs with error protection connect to factory speaker wires with auto turn-on.
Start-Stop Ready
Stable from 10.5 to 16.5 volts through engine start-stop cycles.
