Owners
In 2018 we started 309 Custom Audio out of Dirk's garage. In the beginning it was just Chris and Dirk working predominantly on Victory Motorcycle audio and maintenance. We quickly found a need for custom install parts for Victory's and began developing and manufacturing items to aid in installations and adding additional, larger than factory equipment. Soon after we began offering all the same services for Harley Davidson and other manufacturers. This is the point that John really stepped in with his wealth of knowledge on Harley Davidson's. He answered any questions we threw at him and spent a lot of his free time in the shop with us. As our schedule began getting busier and busier we knew we needed help. We went to John with a proposal to take a leap of faith, leave his job and become a partner in what is now 309 Custom Audio Inc. In 2022 we built and moved into our new shop. The new shop more than doubled our room and allowed us to take on more projects as well as the room to get back into car audio which is where Dirk's audio journey started back in 1994. We take pride in developing and providing excellent products, amazing customer service, clean, quality and timely installs as well as super fast shipping.
