VW T5, T6 and T6.1 Audio Upgrades


VW T5, T6 and T6.1 Audio Upgrades.


We have developed a range of great sounding audio system for the T5, T6 and T6.1 with minimal impact to the vehicle interior. All of the systems use hi-quality componenets combined with hi-end installation techniques to achieve the very best in sound quaity.

The VW T5, T6 and T6.1 Premium Audio Upgrades utilise Audison front components speakers fitted with full acoustic treatment of the doors, this is a 3 or 4 layer system depending on the audio option chosen. 

When installing the acoustic treatment the inner door is completely stripped down to allow access to the back of the outer skin of the door, this is then treated from the inside using Skinz water proof sound proofing, then the regulater panel is refitted and treated in the same way as seen in the image below (left)

Next, the entire back of the door card is treated with the same moisture proof Skinz sound proofing, this in total forms 3 layers of sound proofing.

Lastly, the Voce based systems (Systems 3 and 4) are treated with a 4th layer of DoDo Mat, sound absorber, this can be seen in the centre image below.


The position and angle of a tweeter can dramatically effect its frequency response at the listening position, the T6 and T6.1 both share a very resrictlve grill, placing the tweeter behind this grill has a very negative effect in terms of high frequency performance, to combat this we fabricate a custom tweeter mount which is trimmed in Alcantara and set back in the base of the A-Pillar. In the T5 we are able to retain the factory locations on the dash top.

This not only makes a huge difference to sound quality but looks very asthetically pleasing as can be seen from the right hand image above.

Systems 3 and 4 are powered by an Audison digital amplifier; this amplifier is perfectly matched to the speaker system, it’s Class D so very efficient. It’s compact, powerful and the sound quality is second to none. We install the amp neatly under the passenger seat, once its set up there is no need to access it in the future.

The amplifier is wired using high grade, solid copper, power and speaker cables; this is again important in terms of performance and reliability.

The first  image below shows the amplifier and the DSP (used in a System 4) as well as the passive crossovers for the new front speakers, everthing is mounted neatly under the off side front seat.

 JL Audio XD500/3v2 Mounted In VW T6.1      Subwoofer mounted under T6 Passenger Seat     


The JL Audio CP106 Subwoofer is used in the System 3 and 4 to produce controlled, punchy low bass, the driver is mounted under the seat in a down firring configuration, this is extremely solid and the effective.

The second imgae above shows the completed subwoofer mounted under the seat, the third image shows the subwoofer before mounting.

The System 4 utilises the Hertz H8 DSP, the digital sound processor enables the system to be "tunned" to the vehicle, it also allows the system to be time aligned, this creates an unbelievable sound stage with breathtaking imaging capabilities; instruments and vocals are projected up and forwards with pinpoint accuracy, this is an effect that has to be heard to be believed.

We have several demo cars, two of which are equipped with DSP systems allowing for the demonstration of this incredible piece of equipment.
