Car Audio One on Chula Vista's Third Avenue has operated as a mobile electronics and vehicle customization shop since 2009, stocking Kenwood, Kicker, and JVC product lines for cars, trucks, and marine vessels. Ceramic Pro and Nano Ceramic window-tint films applied at the shop block infrared heat and 99% of UV radiation, an interior-protection layer that complements the exterior paint-correction work at Foamy Bros Auto Detailing. Installation services span Apple CarPlay and Android Auto head-unit retrofits, hardwired dash-cam integration, remote-start modules with smartphone control, and custom subwoofer enclosures shaped to specific trunk geometries. The Third Avenue Village location also builds full truck audio and lighting packages, an overlapping off-road-build capability shared with 4 Wheel Parts on the eastern side of Chula Vista. Custom SPL competition builds incorporate dual 12-inch subwoofers, Class D monoblock amplifiers exceeding 2,000 watts RMS, and closed-cell foam sound-deadening treatments to isolate cabin resonance below 40 dB at idle.
