Custom Audio Installation in San Marcos

When off-the-shelf parts won't fit or won't sound right, we build it. Custom subwoofer enclosures sized for your exact trunk and tuned for your specific sub model. Fiberglass amp racks shaped to fit complex spaces. False floors with concealed wiring and pop-up access panels. Stealth panels that hide subs in spare-tire wells, behind seat backs, or in cargo-area side panels. Full integrated trunk builds with LED lighting, plexi viewing windows, hidden battery banks, and custom upholstery. Every build is designed for your specific vehicle, measured, sketched, and signed off by you before we start cutting MDF. The shop's full custom toolkit is in-house: CNC routing for cabinet panels, fiberglass layup for organic shapes, vinyl wrap and carpet upholstery, suede and leather work for premium finishes, plexi cutting and edge polishing, LED routing with smartphone-controlled color changes, and full electrical work for show vehicles requiring isolated battery banks. We build for daily drivers, weekend show cars, sound-quality competition vehicles, and SPL competition builds. Simple sealed boxes turn around in a couple of hours; full custom trunks with multiple subs and lighting take 1 to 3 days depending on complexity. Lifetime warranty on the build, plus customer involvement throughout the design phase.
