Why drivers upgrade

Bass that hits hard and stops on time.

Big power is easy. Controlled power is not. The NX800.1 pairs 800 watts with the filtering that keeps a subwoofer tight, protected, and tuned to your car.

01Power with headroom

Power with headroom

350 watts at 4 ohm, 550 at 2 ohm, 800 at 1 ohm. Digital Class D with under 0.02% distortion, so the impact stays clean at any volume.

02Filtering that protects the woofer

Filtering that protects the woofer

A 10 to 50 Hz subsonic filter stops wasted energy below the box tuning, a 50 to 250 Hz low pass keeps the sub on bass, and 0 to 18 dB of boost at 40 Hz sets the feel.

03Remote in the box

Remote in the box

The bass level controller is included. Mount it in the dash and adjust sub level for every track without opening the trunk.

Everything a serious subwoofer install needs, remote included.

Everything a serious subwoofer install needs, remote included.

Bass Remote Included

Dash mounted level control ships in the box.

Installation

Three steps to serious low end

1

Connect

Run 4 gauge power and ground with an 80 A fuse, then plug the high-level harness into your factory rear speaker wires. Auto turn-on handles the rest.

2

Mount

At 3.5 by 7.3 inches it fits beside the sub box or under a seat. Class D runs cool with no fan.

3

Tune

  1. Set the low pass around 80 Hz, the subsonic to your enclosure, add boost to taste, then ride the level from the included remote.

Drivers who wanted more and got control with it.

Turned my Prius into a concert hall. Clean, powerful, and hit way harder than expected. The DSP tuning made the factory speakers sound like a whole new system.

Love the Musway combo. The M6 with the MG speakers went from basic to next level real quick. Clean install, clear highs, and the mids finally have body.

Sound is as impressive as the way the amplifier looks. Tight, deep bass that never gets muddy, and the build quality is exactly what you expect from German engineering.

My Tundra sounds like a whole different truck now. The myCon controller makes switching presets effortless and the support team answered every question.

Kept the factory head unit, added the M6, and the difference is night and day. Vocals sit right in front of me now instead of down by my knees.
