In recent years, the Italian brand Steg has focused significantly on sound systems for Mercedes-Benz, BMW, Tesla, Audi and Volkswagen cars. It has developed a series of high-end OEM speakers, which are intended for the latest Mercedes, but also for BMW, where there is a specific mounting of the speakers. These speakers are Plug & Play. Steg also offers standard 165mm car speakers and manufactures car subwoofers and amplifiers. We must not forget about quality DSP processors either.
