Can the original 4-ohm speaker be replaced with a 2-ohm one?

Yes, the original 4-ohm speaker can be replaced with a 2-ohm one. Here is an introduction to car speakers: Working principle: The car electric horn produces sound through the vibration of a metal diaphragm. The car electric horn consists of an iron core, a magnetic coil, contacts, an armature, a diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating a magnetic force that pulls the armature down, forcing the diaphragm to move. The movement of the armature opens the contacts, interrupting the current and causing the magnetic force of the coil to disappear. The diaphragm, along with the armature, returns to its original position due to its own elasticity and the spring plate, closing the contacts again and restoring the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound. Different types: Car horns can be divided into air horns and electric horns based on the sound power; they can be classified into cylindrical, spiral, and basin-shaped based on their appearance; and they can be categorized into high-frequency horns and low-frequency horns based on the sound frequency.
