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.
