Subwoofer Installation in Old Town San Diego

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.

Old Town drivers, a 16-minute run up the I-5 to our Palm Avenue shop. Classic cars, daily drivers, and tour vans all welcome.

Old Town runs a unique vehicle mix, tour vans and trolleys for the historic park, daily-driver sedans for the Presidio Hills neighborhoods, and classic cars heading to weekend cruise spots. The I-5 south from Old Town Avenue gets you to 1610 Palm in about 16 minutes. Common Old Town installs include vintage radio restorations with hidden Bluetooth modules, classic-car audio upgrades that preserve original dash appearance, factory-look CarPlay retrofits for daily drivers built before 2018, marine audio for boats kept near the SD River channel, alarm systems for vehicles that park along Juan Street and Taylor, and dashcam installs for tour and rideshare vehicles. We also handle custom fabrication where modern speakers need to fit older door panels. Walk in any day, free quotes, financing through five lender partners.
