Not only is mtx a universal brand in the united states, it belongs to the mitek sound group, but it is also large in many brands, such as trans-vehicle sound, home sound, professional sound, and wire. The mitek sound group is quite large and its brands are very numerous, including those of mtx, xtant, costic, streetwires, atlas sound, dcm, esoteric, swx, magnum, etc., which are part of the car sound, and with the exception of mtx, xtant and costic are not too familiar. Xtant, on the higher route, was created from the base of the old american brand precisionpower, which was later incorporated into the mitek group, and whose extension machines and horns have been welcomed by many high-level equipment players and are currently represented at the national level by the honghum. Costic, originally a stand-alone brand, has also met the needs of many of the auto-sounding players with low-cost equipment, while its balanced high-end dr series, which has led to the peak of costic’s brand name. Coustic was previously searched for by the gp group and transferred to the mitek group, where it was imported locally by an exhibition electrician and is currently not imported by the manufacturer. Moreover, the brand of streetwires, a specialized liner, although relatively new, is locally used by a large number of self-assembled diys, with a wide range of professional and well-rounded product content, offering consumers many options. Turning now to the leading actor, mtx, the brand, which could be described as the leading brand under the name of the mitek sound group, which was introduced earlier by a well-known agent, bamboo trading corporation, acting as alpine in japan, but only in a short year, when products were less competitive, and when they were introduced in small quantities and for too short a period, did not impress domestic consumers. Since then, mtx products, which are occasionally visible on the market, have emerged, although they are part of parallel efforts by traders that have not been officially introduced by manufacturers. Since last year, after several years of domestic conflict, mtx has been officially introduced into the market by companies that have traditionally operated european-based products.
