Car Stereo Installation in San Marcos

Replacing a factory radio is the quickest and most visible upgrade you can do to an older vehicle. Our techs install single-DIN, double-DIN, 9-inch floating-display, and stock-look OEM-fit head units in nearly any year/make/model on the road today. Every install starts with a vehicle-specific dash kit so the new head unit sits flush in the dash, and a model-specific T-harness adapter so your factory wiring stays untouched and reversible if you ever decide to put the original radio back. Steering-wheel controls, hands-free Bluetooth, factory backup cameras, satellite radio antennas, and premium audio systems all get retained or properly bridged through interface modules. We carry Kenwood, Pioneer, Sony, Alpine, Kicker, and Boss Audio head units, and we'll match the unit to your dash size, your daily-driving habits, and your budget. If you want to keep the factory radio look, we'll spec a stock-look OEM-fit upgrade that drops into the factory dash position so cleanly that nobody can spot it. Wireless Apple CarPlay, wireless Android Auto, dual USB-C charging, dual-cam input for backup-and-dashcam combo wiring, HD radio, SiriusXM, Spotify, and full voice-command support are all standard features on the modern head units we install. Most installs take 1–3 hours depending on vehicle complexity. Lifetime workmanship warranty on every install.
