Sound that fits the way you actually drive.
Baseline is a stereo install shop in Chula Vista — built on the South Bay car culture that raised us. We take one car at a time, treat every install like the owner is going to live with it for years, and don't release a build until it sounds the way it should.
Quiet wiring. Clean grounds. Tuning that holds up at low volume — not just at full tilt.
the way they
should be done — patient, particular, and built to last.

What we install.
Levels SD
An event series by Baseline. Cars, sound, and the gente that keep San Diego car culture alive — one meet at a time.
1-Year strong
From a single lot to a full block. Levels has hit its first anniversary with the same crew that showed up day one.
Built in a Chula Vista garage.
Made for la gente.
Baseline started in a garage in Chula Vista. Today it's a community-rooted stereo shop serving San Diego — every install gets the same care, whether it's a head unit upgrade or a full custom build.
Through Levels, our event series, we put the same energy back into the scene that built us.
