Custom Truck Stereo Systems for Western Star, Kenworth, Mack & Volvo
At AV Concept, we specialize in tailored truck stereo systems for heavy-duty vehicles like Western Star, Kenworth T900/C500/T600 series, Mack, Volvo, Euro trucks, and other smaller trucks with 24-volt systems. Our upgrades include custom 3D printed speaker mounts, subwoofers, and headunit integrations, all tuned to your seated position for optimal sound clarity and bass response in rugged environments.

Why Choose AV Concept Truck Stereo Upgrades?
Our systems are tested in the roughest country conditions, ensuring they hold up to vibrations, dust, and off-road demands. We fit all systems in our workshop in Toowoomba, but can build packages to send directly to you for most popular trucks with support for your local auto electrician to fit the system.
