Tell me about my speakers

There are two sets of speaker terminals behind the speaker. Just connect the horn wire to a set of terminals, with the positive electrode connected to red and the negative electrode connected to black. It is not necessary to connect two red terminals or black terminals at the same time. There is no sound in the tweeter, but the coil is burnt out. You should remove the tweeter, take it to the local electronic market to replace the coil, or buy a new tweeter and install it.

Large-caliber speakers are bass, and small-caliber speakers are treble. A frequency divider is arranged in the sound box and connected with the high and low speakers respectively.
