Amplifier Installation in Kearny Mesa

An amplifier is what makes aftermarket speakers actually breathe. Stock head-unit amplifiers typically deliver around 18 watts RMS per channel, enough for daily-driver volume, but well below what good aftermarket components are designed to receive. Our techs install mono subwoofer amplifiers, 4-channel speaker amps, 5-channel hybrids that drive front speakers and a sub from one chassis, and dedicated DSP-controlled amplifiers for builds where signal processing matters. Every install includes correct-gauge power wire (0/4/8 AWG depending on amp draw) routed cleanly through the firewall, an in-line fuse holder within 18 inches of the battery for safety, ground-loop isolators on factory radios to kill alternator whine, RCA shielding to prevent ignition noise, and final gain-matching using calibration tones and a multimeter. Gains are set with the speakers' RMS rating in mind so the amp runs in its clean range and the system has real headroom. Class-D efficient mono amps start around 500 watts RMS for daily-driver bass; 4-channel amps for full-range speaker upgrades start around 75 watts per channel. Lifetime workmanship warranty on every amp install.
