Founded in 1967, Alpine, formerly known as a joint venture between ALPS Electric and MOTOROLA of the United States, became the standard configuration of Lamborghini audio system as early as 1977, and was the first to obtain ISO9001 certification among the powerful Japanese car manufacturers, and OEM customers include almost all the world's famous car manufacturers such as Rolls-Royce, BMW, and Mercedes-Benz. As the first foreign brand to produce car audio in China, Alpine has been well-known to Chinese consumers since the 90s of the last century, and is still a supplier of accessories for brands such as Guangzhou Honda and BMW Brilliance.
 
At present, Alpine's aftermarket products are still focused on on-board multimedia and DSP power amplifiers, and only the entry-level SPJ series has been updated recently, with a slight increase in low-frequency dive and high-frequency brightness. The flagship Z17PRO, which costs more than 10,000 yuan, is the embodiment of the strength of Alpine's DDlinear technology, which can still withstand the test of loud sound pressure playback at extremely low distortion rate. Despite this, as a predecessor model that has been on the market for nearly ten years, it is still a little tired when comparing it horizontally with other competing products, compared to the model of the thousand-yuan stall, it is more worth starting, and it can be purchased online and offline.
