Subwoofers

A subwoofer install done right doesn't just hit hard — it hits clean. At Auto Audio in Hermantown, Minnesota, we've been building subwoofer systems for over 30 years, and we understand that proper enclosure design, amplifier matching, and tuning matter just as much as the subwoofer itself. Whether you want a compact sealed enclosure that fits neatly in a truck cab, a ported box tuned for low extension, or a custom-built solution for a motorcycle or marine application, our team designs around your vehicle and your taste. We work with Rockford Fosgate, JBL, and other leading brands trusted by enthusiasts and everyday drivers across the Duluth area. From a single 10-inch in a daily driver to a full competition-capable system, Auto Audio builds subwoofer setups that perform reliably — not just on day one, but for years down the road.
