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?

We have improved the manual so that customer can read easily.
