The new entry into the HELIX world! The D amplifier series is modest in only one respect – namely in pricing. Everything else is through and through “HELIX pure” without compromise.Much power, great readings and a bulky equipment package are guarantor for unadulterated, crisp sound experiences!

The features have thought of everything that is important for powerful bass power – the active crossover with subsonic filter, low pass, phase control and bass boost is just as natural as the intelligent high-level input with Audiotec Fischer’s proprietary ADEP circuit. Even a cable remote control for the volume is included. When choosing the right subwoofer, the D ONE is extremely flexible thanks to the 1-ohm stability. And if the power is not enough, you can even combine two amplifiers into one big powerhouse thanks to the master / slave function.

The elegant design not only reveals the origin at first glance, but due to its compact dimensions it also allows easy integration into the vehicle even when there is a shortage of space. So sound tuning is really fun for your vehicle!

Special features:

Intelligent high-level input
Modern, factory-installed car radios are becoming increasingly intelligent in terms of diagnosing the connected speakers. If an amplifier is connected to the radio instead, it usually results in error messages up to the elimination of individual functions (such as faders).
The new Advanced Diagnostics Error Protection (ADEP) circuitry eliminates all of these problems without unduly stressing the radio’s speaker outputs at high levels.
