In 1989, KOSO was registered as a trademark of Tong Ya. The name KOSO is derived from the Japanese words for "conception" and "high speed"; conception represents creativity, while high speed represents high-performance expression. Combined, it reflects the company's hope to use creativity to create high-performance products! - Spirit - The brand spirit KOSO pursues is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently hold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone. - Brand Journey - Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly spurs itself on by improving its own technology. We firmly believe that brand image and product quality are synonymous! Therefore, the company has strict requirements for product development, production processes, and quality control, hoping to achieve the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, and hopes to become the next world number one from Taiwan within ten years, another pride of Taiwan. - Exhibitions and Certifications - Tong Ya Electronic began exhibiting in Italy in 2001, gradually stepping onto the international stage, bringing KOSO's dedication and professionalism to the world, and striving to convey an image of high quality and innovation. It obtained TS16949 international certification in 2007, and ISO 14001 and ISO 45001 international certifications in 2024. In the future, it will continue to create more moving products. Every product launch requires actual installation testing, which is the strictest quality inspection method. No matter how well a product is designed, once it is actually installed and used, it is a test of quality. To further improve quality and actual product testing, we participate in international competitions. However, every award is an affirmation of the product, because it is a modification that does not allow for errors. We are so rigorous about quality. Test reports and product measurement charts are also our demonstration of the results of customer installation. It is precisely because of this caution that our products can show better quality time after time. - Equipment and Checkpoints - Our pre-inspection for every product uses the most advanced technical machinery, setting different conditions to simulate and conduct tests, such as vibration tests, waterproof tests, etc. All partner manufacturers who have participated in the inspection process agree with our principles of quality control and trust the test results. What is valuable is that while the product is subjected to tests like passing checkpoints, we also add different conditions and make adjustments based on the actual environment, combined with user-friendly operation to present the most realistic tests of the product and the improved quality after correction.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.

[Notes before ordering] Before ordering, please double-check the color, size, and other information you wish to purchase. Most products have delivery times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment. If an order cannot be established due to factors such as manufacturer stock shortages and temporary inability to deliver, it will not be established; if the order is not established, no fees will be charged. Please understand that manufacturers may unilaterally change specifications or exterior designs, resulting in packaging or product styling that differs from the images on the product page. If a manufacturer unilaterally changes product design or specifications, causing the product to fail to perform the functions expected at the time of ordering, please consult our customer service for subsequent handling. Products go through multiple shipping processes from order to shipment, so packaging may be deformed or damaged during transport, but the product itself remains intact and usable.
