Luxury sound

If you want the best possible car audio system with no compromises in sound quality, then BRAX's NOX4B 4-channel amplifier should be powering your music. This gorgeous, hand-crafted workhorse brings an unprecedented level of high-fidelity amplification into the mobile environment. The NOX4B can put out 105 watts RMS to each of your front and rear speakers or components. Bridged for 2-channel operation, the NOX4B punches out up to 380 watts RMS each to a couple of subwoofers.

Build-quality that's off the charts

The massive heatsink tells you right away that this is a serious amp. Inside, the multi-layered circuit board is laid out in short, dedicated signal paths to deliver only the purest signal in the fastest time. Brax uses silver solder to secure each discretely mounted component for the best conductivity possible between them. Gold-plated connections eliminate corrosion to keep the signal flowing freely in or out of this amplifier.

Hi-fi features

Because handling music properly takes such a delicate touch, you won't find any crossover filters or bass boosts in this amp to color or sidetrack the sound from its final destination. Two separate power supplies ensure stability and dependability. The output power transistors have been hand-selected and measured to match each other so your music will sound consistent and strong. You'll want to display this amp proudly in your system. Hand made in Germany, each NOX4B comes with its serial number custom milled into the top nameplate.
