A pristine, dynamic, and high-fidelity listening experience without compromising vehicle integrity.

The Problem

Your stock car stereo system looks great, but it sounds average with those cheap, dull factory installed speakers, and you'd really like overall better sound without replacing the entire head unit or cutting holes.

The Solution

We can supply and install a range of pristine, dynamic, high-fidelity, German made, plug & play DSP's and components specifically made for your car and custom-tune it to suit your listening preference.

The Experience

A well balanced, perfectly timed sound stage with deep bass, crisp mids and clear music reproduction. Every vehicle is treated uniquely to enhance the owners unique listening experience.

The Guarentee

We are professional audio engineers, not just installers, and as such, your vehicle's sound is tuned with both ears and high-end equipment to deliver you a concert-like listening experience. 

A full custom-tuned, audio enhancement specific to your vehicle and listening preference.

Plug & Play
Sound Experience

MATCH Plug & Play line provides maximum sound improvement of the original audio system with minimal installation effort. 

The huge advantage: The vehicle remains as it is. Everything will be installed without trace and be removed quickly – an essential aspect especially for leasing cars.

MATCH Plug & Play components are the perfect solution for sound at its best from the OEM/factory radio.

The DNA of
Perfect Sound

HELIX Car Audio components combine perfect music enjoyment and great sound experience with a price-performance ratio, which was described as sensational by the national and international press.

With a mature product program – from entry-level to leading-edge components – HELIX quintessentially fulfills our primal urge for rhythm and sound.

Music Is

“Compromises” are absolutely taboo in the development and production of every single BRAX product – only the finest human selected materials are used, which are perfected with precision craftsmanship in Schmallenberg to create audible words of art. And of course, we only use “made in Germany” components.

BRAX will now, and in the future, remain a synonym par excellence for enjoying music in its finest state.

Frequently Asked Questions

Does an audio system need to be installed by a specialist?

We always recommend having it installed by one of our professional audio engineers. However, with the plug &  play products everything is designed for a simple installation. As such we are happy to sell this equipment direct to you.

How do I set the sound controls of my car radio after installing a VA Audio Technic sound system?

We generally tune our vehicle-specific setups in such a way that the optimum sound is achieved when all sound controls on the car radio are in the middle positions (“linear”). Of course, you can still use the tone controls to adapt to your own listening taste, but you should first select the linear position after installation, because in most cases, our sound setup for that vehicle has been tuned to perfection.

Are there problems with the speaker diagnostics and detection by my original car radio when I am driving a HELIX amplifier through the highlevel inputs?

In recent years, we have optimised the input circuit of our amplifiers to prevent this. The loudspeaker diagnostics in almost all factory installed radios is now very complex, so it must already present some resistance in the amplifier to avoid entries in the fault memory of the vehicle. Our products proprietary circuits “ADEP” and “ADEP-SB” are unique in this regard and have a good track record of avoiding speaker detection problems.

Do you absolutely need a DSP in a sound system or is it synonymous without?

Those who want to get the most out of the existing speakers will look to use a signal processor (DSP) – whether integrated into the amplifier or as a separate component. Of course, the active crossover in our amplifiers that do not include a DSP still result in a great sound, but a DSP has quite a different way of influencing sound due to its enormous range of functions. Speak to one of our engineers about this in more detail.

Why do BRAX amplifiers not have an integrated crossover or other filters?

Sound enthusiasts today are betting on the power of DSP technology with its almost limitless and highly accurate set-up options. External signal processors eliminate the need for conventionally designed integrated filters, especially for amplifiers in the absolute premium segment. For this reason, BRAX amplifiers are designed and built with the shortest possible signal path. This design ensures that every possible component which could affect the desired result, which is an unadulterated sound reproduction, is removed.

Will the original speakers in my vehicle be overloaded and possibly damaged by the more powerful amplifier of a MATCH or HELIX Plug & Play sound system?

In general, the load on the original speakers after installation of a VA AUDIO TECHNIC sound system is even lower because, despite the higher maximum power of the amplifier, they no longer have to reproduce the low frequencies. This task is instead handed over to the subwoofer, which should not be missed out in any high-end audio system. Couple that with clean, balanced audio and you’ll be amazed at your new sound stage.

Is a separate signal processor (DSP) better than a solution integrated into the amplifier?

The decision depends solely on the desired configuration. If an amplifier such as the P SIX DSP or the V EIGHT DSP meets all the requirements for your installation in one device, there is no reason to choose one of our separate DSPs for use with a dedicated amplifier. If the number of channels required or the desired output power cannot be achieved with the integrated solutions, then the separate configuration is the best path forward. All HELIX DSP products use only the highest-performance processors (DSPs) of the latest generation with 64 Bit resolution.

Why are BRAX speakers no longer offered with passive crossovers?

In the absolute high-end segment, the demand for passive crossovers has declined significantly in recent years – and not without reason. If you want to achieve the absolute tonal optimum, you cannot really avoid using a fully active system of control for the speakers. Anyone who still prefers a passive switch, we are happy to provide the appropriate circuit diagrams for you to build your own unit. All HELIX DSP products use only the highest-performance processors (DSPs) of the latest generation with 64 Bit resolution.
