The Italian brand Steg has focused significantly on the sound system of Mercedes-Benz, BMW, Tesla, Audi and Volkswagen cars in recent years. It has developed a series of top-quality OEM speakers that are designed for the latest Mercedes, but also for BMW, where there is a specific speaker mount. These speakers are Plug & Play. Steg also offers standard 165 mm car speakers and produces subwoofers and car amplifiers. We must not forget about high-quality DSP processors.
