- Paralel Kablolama: Connect both positive terminals together and both negative terminals together. This results in a 2 Ohm load (4 Ohm / 2 = 2 Ohm).
- Seri Kablolama: Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining two terminals (one positive, one negative) are then connected to the amplifier. This results in an 8 Ohm load (4 Ohm + 4 Ohm = 8 Ohm).
Use appropriate gauge speaker wire for connections. Ensure all connections are secure and free from shorts.
