The company specialises in audio devices. Meinmacht makes in-car audio for various manufacturers. It is probably based on Blaupunkt. It could also be based on Behringer due to the fact that both logos share the same triangular shape design, and the fact that they also make professional speakers as seen in Nightclubs.
Meinmacht is also involved in sponsoring racing activities. In the enhanced version of GTA Online, the Meinmacht livery is available on numerous vehicles, as a customizable feature on the Elegy Retro Custom, Comet Retro Custom and Visione. Their logo also appears on a poster inside "Branded" Vehicle Warehouses.
