IASCA Vietnam has become an official member of IASCA World since 2019 with the first IASCA International Judge Training held in October 2024.

After a period of studying and learning from previous countries, IASCA Vietnam officially organized the Audio Competition on October 26, 2025 in Long Bien Dist., Hanoi with the main purpose of promoting the Automotive Audio industry, while improving the capacity of retailers to reach more customers. IASCA is famous for its nice test track but hard scoring judging, bringing a new breeze to the automotive audio field and is a challenge that any car audio lover wants to conquer.

The tournament brings together nearly 50 competitors with sound configurations from basic to Hi-end, competing in more than 105 different Judging with 14 Categories. The participants vary from car audio enthusiasts to Local Installation Shop as well as Global Brand Distributors. The tournament has the presence of leading international audio brands such as Focal (France), Rebec (China), MTS (Italy), DynAudio (Denmark), Alpine (Japan) …

The international Judge consists of 4 experienced referees from countries in the region and the presence of the president of IASCA China-Taiwan & Japan, the strongest countries in the region to support. The competition categories are also very diverse, from the Novice category for beginners to the highest category, Expert, with 2 seat judging practice, appearing for the first time in Vietnam.

For the first time in Vietnam, there is a 2 seat Judging for both the driver and passenger, which is very challenging compared to the usual installation and arrangement of equipment for only 1 judging position. However, the 2-seat judging format is very familiar and suitable for the music listening requirement of Vietnamese customers.

New categories suitable for the market such as OEM for original car speakers as well as music sources using Android screens & using DSP integrated amplifiers on cars are, also implemented for the first time in IASCA Vietnam which quite close to the market trend in Asia.
