This is difficult to say, because for different cars, different spaces, and the combination of speakers and other accessories, the effects are also very different. The new Tianma amplifier I used was not very good at first. I know how to adjust it. It is said to be bbe sound effect processing and multi-knob sound effect adjustment. It seems very powerful, but it is really very powerful. I didn’t know how to adjust it at first, so I adjusted it slowly. It’s best to adjust the music style that suits you best, and it’s also very delicious. Oh~ I bought the Xintianma T8 model, and I started by adjusting the midrange. Right, the mid-bass, mid-range and treble are not moved, the treble is slightly raised, and the bass is slightly increased. On this basis, adjust slowly to create your own music
