The Toure amplifier in Britain is not good. Toure has a very good BOSE sound, but without a good sound source, even the best sound can't play its due role, and he is not satisfied with all the sound quality effects now. Multi-channel music has two audio formats, dts and Dolby AC3, which are generally used in cinemas and high-fidelity home cinemas, as well as a few high-end luxury flagship models. This decoding function is only available on the DVD player stereo of Toure's original car.
