About Stereo Base
Three decades on Mission Boulevard
Stereo Base opened in 1996 with a simple idea: sell good gear, install it properly, and be straight with people about what their car needs.
Today we’re a one-stop shop for car audio, window tint, paint protection and vehicle security. We handle OEM integration, custom audio, alarms and remote start, radar detectors, dash cams, and Apple CarPlay and Android Auto upgrades.
Our trained, certified product specialists and installers have decades of combined experience, and they’re the same people you’ll talk to on the phone and at the counter.
What hasn’t changed since day one
Expert technicians
Every car audio technician here has more than 10 years of experience. Installs are done by our own team, never subcontracted.
Product knowledge
Our sales team knows which speakers, amps and processors sound great together, and will tell you when you don’t need an upgrade.
Satisfaction, guaranteed
We explain the work before we start and walk you through it at pickup. If something isn’t right, we fix it.
If it has a battery, we can probably wire it
Daily drivers, classics and weekend toys. We’ve worked on Hondas, Toyotas, Chevys, Fords, Teslas and Porsches, and plenty in between.
