Subwoofer Installation in El Cajon

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.
