Active sound systems create a deeper, more distinctive vehicle sound using electronically controlled external speakers rather than relying solely on the factory exhaust. Designed for a wide range of modern petrol, diesel, hybrid and electric vehicles, these retrofit systems can offer multiple selectable sound profiles, adjustable volume and app-based control while retaining the original exhaust system. Browse complete active sound packages, speakers, controllers and upgrade components from specialist manufacturers, with options suitable for everything from subtle OEM-style enhancement to a much more aggressive performance sound.
