Two years later, 1996, we set up our own factory named Trisonic, producing car speakers. All the money earned before and between the two years was launched into building the workshops & buying equipments. Fortunately facts proved we are right - high investment in controlling the quality means developing. Also two years later, we extended to almost all the car audio products. Meanwhile, we still persisted in our consistent idea-high quality, best service and reasonable price-and we continued developing.
