Supertech Electronics is an Australian owned and operated electronic repair shop that specializes in repair of audio visual equipment. About 80% of our repairs are factory car stereo systems. The business evolved in 1992 when we noticed a lack of service and support for factory car audio systems. We have repaired over 25,000 car stereo systems since accurate records were started in 2002. That’s an average of around 1,800 factory car stereo repairs per year.
