Why I feel the sound of this air horn is low?

Step1: There is a difference between positive and negative poles in the wiring of the terminal under the air pump. Please check whether there is a reverse connection.

Step 2: Check if the harness（blue/white wire to your original horn wire） connected to the car device is loose.

The manual of the air horn is hard to read?
