With roots tracing to 1954, Al & Ed's Autosound on Jackson Drive in La Mesa near Grossmont Center carries one of the deepest aftermarket mobile-electronics catalogs in East County, stocking JL Audio, Focal, Alpine, Kenwood, and Rockford Fosgate lines. The shop holds certified Intoxalock installation designation for ignition-interlock device fitting alongside its broader security-system portfolio, an automotive access-control specialty adjacent to the transponder-programming services at Kwik-Key Locksmiths in the La Mesa area. This independently owned franchise handles car stereo upgrades, amplifier wiring, subwoofer enclosure fabrication, backup-camera integration, and ceramic window-tint application with a lifetime installation warranty on all labor. Vehicle-security installations include GPS tracking modules, dash-cam hardwiring, and alarm systems that integrate with the 12-volt architecture without disrupting OBD-II diagnostic readiness — the same diagnostic bus accessed during routine service at Valvoline Instant Oil Change on Fletcher Parkway. Custom fabrication projects incorporate fiberglass molds, MDF baffles, and CNC-routed enclosures to achieve vehicle-specific subwoofer alignments tuned to cabin volume and port-frequency targets.
