Subwoofer Installation in Ocean Beach

Bass is the most-requested upgrade in our shop, and there's a wide spectrum of options. We install 8", 10", 12", and 15" subwoofers in pre-fab sealed and ported enclosures, custom-fab boxes designed for your specific trunk, slim under-seat models for trucks where cargo space matters, dual-sub setups for SPL builds, and stealth-style enclosures that hide behind seats or in spare-tire wells. Every sub install includes proper power-wire routing through the firewall to the battery, a fused distribution block within 18 inches of the battery, big-3 alternator wiring upgrades on high-power builds, and gain-matched amp tuning so your bass actually hits without rattling the dash apart or distorting at high volumes. We tune by ear and by meter, set the low-pass crossover correctly for the box, and check phase between sub and front-stage speakers. We carry Kicker, Alpine, Boss Audio, Memphis Audio, and Sundown Audio subs and can spec a setup from a clean daily-driver thump to a full SPL competition build. Common subwoofer-and-amp combo installs take 3 to 4 hours; full custom-fab builds run 1 to 3 days depending on complexity. Lifetime workmanship on every sub build, even on customer-supplied gear.

Ocean Beach drivers, a 22-minute drive up the I-5 and west on the SR-8 to our Palm Avenue shop. Beach cars, vans, and surf rigs all welcome.

Ocean Beach has a vehicle mix all its own, classic VW buses, Sprinter conversions, surf-rack-equipped Tacomas, and daily-driver sedans that handle the salt air year round. From Newport Avenue, head east on the SR-8, then south on the I-5 to Palm Avenue, about 22 minutes total. Common OB installs include marine-rated speaker upgrades for vehicles that live near the beach and the salt, hidden Bluetooth retrofits for vintage VWs and Westys, custom fabrication for Sprinter and van conversions, weatherproof subwoofer enclosures for vehicles with sliding doors, alarm systems for cars parked overnight by the pier, and dashcams for daily commuters. We also handle audio repairs on systems where corrosion has caused issues. Walk in any day, written quotes on the spot.
