2022 VW Transporter T6.1 – Full HELIX Audio Build 🔊

This customer travelled all the way from Bristol looking for a premium sound upgrade while retaining the factory stereo.

The goal was simple – an OEM-looking installation with incredible sound quality, all digitally tuned to suit the customer’s listening preferences.

The build included:

🔊 HELIX i5 component speakers
🎵 HELIX i5 tweeters
🔇 3-stage sound insulation for improved clarity and reduced road noise
📦 HELIX 10” Transporter under-seat subwoofer enclosure
⚡ HELIX Amplify 206 DSP amplifier

The entire system was professionally DSP tuned, time aligned and EQ’d to create a precise soundstage with deep, controlled bass and exceptional clarity.

As a finishing touch, we fabricated a discreet OEM-style bass controller into one of the factory blank switch locations, giving the customer instant control over bass levels whenever needed.

Another Transporter leaving SJ Concepts with an OEM finish and a huge improvement in sound quality. 🔥

1994 Honda NSX in for a full custom audio & multimedia upgrade.

With no off-the-shelf fitting kit available, we custom fabricated the stereo facia to house a Kenwood 8021DABS, finished in OEM-style polyurethane paint.

The factory Bose system was replaced with Helix i7 coaxials, Helix i5 rear fill, a custom-fitted Vibe 8” subwoofer in the original kickwell location, and a Match UP 4DSP for full time alignment and digital EQ.

A rare car, upgraded properly while keeping the original character.
