Sony · 2015
The official Sony Colombia demo car — a red compact hatch running a full Sony system, with red-and-black interior customization, custom door panels and a trunk enclosure. Built and tuned by Galaxi Sound to represent the brand.
What we did
This compact hatch is one of 14 demo and show builds in the Galaxi Sound portfolio, and one of 2 built around Sony equipment. It dates from 2015, and the 16 photos in the gallery above show the finished work in detail.
Below, each part of the work list is explained in plain terms — what it involves, and how the same idea can be scaled to a car you drive every day.
Sony, the Japanese electronics maker, has long made car audio as well — head units, speakers, amplifiers and subwoofers — including the Xplode line aimed at high-output systems.

Plain-language notes on every item in the work list — what it is, why it is done, and what to know before doing the same on your car.
A manufacturer's demo car exists so people can see and hear the brand's equipment in a real vehicle instead of on a display wall. It has to look like the brand, sound the way the brand wants to be heard, and hold up to being shown, driven and listened to over and over. Building one means working to the brand's image as well as to the installer's own standards.
Car audio brands guide →Demo cars are built to showcase a brand, so that brand's equipment is the centerpiece of the system. On your own car, mixing brands is completely normal. What matters is that the parts are matched: speaker power handling to amplifier output, subwoofers to their enclosure, and the whole system to your car's electrical capacity and the way you listen — and then that it gets tuned for that specific interior.
Car audio brands guide →Custom interior panels tie the audio system to the rest of the car. They are usually shaped from MDF or fiberglass, then wrapped in vinyl or fabric, or painted to match the build's color scheme. Beyond looks, they give speakers, displays and controls a clean place to live and hide the wiring behind them. The key is fit: panels have to line up with the factory trim and stay quiet on rough roads.
Custom car audio installs →A subwoofer only performs as well as the box it's in. A custom enclosure is built to the internal volume the driver needs, then shaped to the space the car actually has — trunk floor, side walls, rear deck or cabin. Fiberglass lets the box follow curves no flat MDF panel can, which is why show builds lean on it. On a daily driver the same skills can go the other way: a stealth box that hides the sub and keeps the trunk usable.
Subwoofer & enclosure installs →Factory doors are designed around small speakers and thin plastic trim. A custom door panel gives larger or additional speakers a rigid, sealed mounting surface, aims them better and turns the door into a design element with its own colors, trim rings or lighting. Done right, the panel still clears the window mechanism, handle and lock, and it stays solid and rattle-free after years of opening and closing.
Speaker & door panel installs →Show and demo cars follow the same sequence as any serious system, just taken further. First comes planning: what the car is for, where the equipment can live, and how the audio will fit the look of the build. Then fabrication — enclosures, panels and trim made to fit that specific car. Then wiring, with correctly sized power cable, fusing and clean signal runs. Last comes tuning: gains, crossover points and time alignment set for that interior, by ear and with measurement tools.
The team behind these builds holds IASCA championship titles and an SPL world record, and the same crew handles everyday installs at our Kendall shop — from a head unit swap to a full custom build. On daily drivers we keep installs lease-safe, with factory-retention harnesses and reversible wiring, so the car can go back to stock.
