California Audio is awesome, super helpful and quick at getting people in and out. I've been going to them for two years and I'll always go to them for everything. They have put in a sound system, security system and camera in my truck--and they will also do window tinting soon. I think their prices are pretty good because I've checked out other places where prices are a lot higher--so they aren't ones to overdo prices.
Alan and Trevor are good, super fast and quick every time I go in. I like that the owner Alan is always there to support the shop and answer questions, because that's not something other people who own audio shops do.
