After years of servicing the needs of the greater Santa Rosa area Kustom Kar has decided to expand. As Napa counties newest car audio store, Kustom Kar looks to progress the level of service in Napa to new heights and bring the same talent, expertise, and customer service that people have grown to associate with our Santa Rosa store. Our talented staff was assembled taking great care to make sure every job is taken care of with the utmost care and knowledge. Be it your very first car or your new luxury super car we can assure you it will be taken care and handled as if it were our own. At Kustom Kar we have put extensive research into getting the best possible products from the largest names in our industry such as Pioneer, Focal, JL Audio, and Arc Audio.

At Kustom Kar you always get the very best product for your money. We sell and install systems that fit a wide range of budgets but all have one thing in common; if we wouldn't put it in our own vehicle we won't put it in yours. After a dozen years in business and several thousand installs we truly know what's good and what's not. We don't even stock products that will disappoint our customers. Our customers have the security of knowing that they will always get great products for their money and the best installation in the industry... Every time.

Our San Rosa location faces Flower Ave. Our suite is located in the same complex as Johnny Franklin Muffler.
