Dear all, I am the newbie here and would like to ask if some of you have change the audio system of the car. The stock 7-speakers setup is really poor that the cost of front 6' speaker cost about 50HKD each only. I would like to change some of the speakers and add a sub woofer and amp to the car so i went to Monkok, but those shops are unfamiliar with this electric car. Does anyone know technician doing this and which brand of the sound system do you use? How is it? Thanks tons!
