Welcome to Jr Car Audio
From crystal-clear stereo upgrades to complete security system installations — we bring passion, precision, and honest service to every vehicle that rolls into our San Jose shop.
Our Story
Jr Car Audio was born from a simple belief: every driver deserves a car that sounds as good as it looks. Located on South First Street in San Jose, we've spent years turning ordinary rides into extraordinary experiences — one speaker, one wire, one satisfied customer at a time.
We're not a chain. We don't rush jobs. When you pull into our shop, you get hands-on attention from people who genuinely care about the work. That's the standard we set for ourselves, and it's the reason our neighbors keep sending friends our way.
"We treat every vehicle like it's our own — because that's how we'd want our cars treated."
What We Do
Whether you're upgrading your daily driver or building something special, we offer the expertise and parts to make it right the first time.
Single-DIN and double-DIN head units, component speakers, subwoofers, and amplifiers — matched and tuned to your taste and budget.
Clean, professional wiring from start to finish. We route power and signal cables with care, ensuring no interference and a factory-finished look.
Protect your investment with reliable car alarms, remote starters, and anti-theft systems installed by technicians who understand vehicle electronics.
Electrical gremlins, flickering screens, dead radios — we diagnose and fix car audio and electronics problems others turn away from.
Backup cameras, touchscreen displays, and screen upgrades — seamlessly integrated so they look like they belonged there from the factory.
Have a vision? We'll help you design the perfect system — from boutique sound to competition-level bass — and bring it to life in your vehicle.

Our Work
Real installations, real vehicles, real results. Here's a glimpse of what we do every day.
Kind Words
We let our work speak for itself — but these notes from our customers mean a lot.
"They transformed my old sedan into a mobile concert hall. The sound quality is incredible, and the wiring is so clean you'd never know anything was added. Truly talented team."
"I brought my truck in for a remote start and alarm — they explained everything, gave me a fair price, and had it done in a few hours. No pressure, no nonsense. I'll be back for speakers soon."
"Finally a shop that actually listens. They helped me choose the right speakers for my budget and made them sound amazing. The whole process was comfortable and transparent."
