Kicker
A BMW M3 done as a Kicker show car — full yellow Kicker wrap, custom wheels, lowered stance and a Kicker system to match. Serious output with the fit and finish a performance car deserves.
What we did
This BMW M3 is one of 14 demo and show builds in the Galaxi Sound portfolio, and one of 5 built around Kicker equipment. The 11 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.
Kicker is an American car audio brand from Stillwater, Oklahoma, recognizable by its yellow-and-black branding and known above all for its subwoofers and amplifiers. That strong visual identity is why Kicker demo cars so often wear the brand's colors.

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 vinyl wrap changes a car's color or adds graphics without repainting. Brand demo cars use it to carry the manufacturer's colors, and it can be removed later; while it's on, it shields the paint underneath from sun and light scratches. Quality comes down to surface prep, clean edges and seams, and post-heating the film so it holds its shape in the Miami heat.
Car wraps in Miami →Wheels set the stance of a build as much as paint or a wrap does. Choosing them is about more than style: diameter, width and offset decide whether the wheel clears the brakes and suspension and sits correctly in the fender, and the overall tire diameter affects speedometer accuracy. New wheels should be mounted and balanced properly, followed by an alignment check.
Tires & custom wheels →Lowering brings the body closer to the ground for a tighter stance and a lower center of gravity. It is usually done with lowering springs (a fixed drop) or coilovers, which let you adjust ride height and, on many kits, damping. Any change in height changes the alignment, so a lowered car should always be aligned afterwards, and wheel fitment has to be checked so the tires don't rub the fenders.
Lowering & coilovers →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 →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.
