The incoming cassette changed the mp3 input and I felt that the sound quality was a lot better. But I feel that the bass is not enough, I added a five-inch active subwoofer, placed at the bottom of the co-pilot seat, 80 yuan for two high notes. The input is taken from the output 24 and 25 of the PT2313 of the cassette (theoretically, the output is 22, 23 or 24, 25, but the 24 and 25 feet are easy to be wired), so that the volume can be controlled through the panel, and the effect is better. Shocking feeling. Friends who like bass can refer to! ! (The radio is also output through there). The following is the circuit diagram of PT2313
