3. Sambungan Pendawaian
The Kicker 45L7R122 subwoofer features a Dual Voice Coil (DVC) 2-ohm configuration. This allows for various wiring options to achieve different impedance loads at your amplifier. The most common configurations are:
- 1-ohm Load: Wire the two 2-ohm voice coils in parallel. Connect the positive terminal of coil 1 to the positive terminal of coil 2, and the negative terminal of coil 1 to the negative terminal of coil 2. Then connect the amplifier's positive output to the combined positive terminals and the amplifier's negative output to the combined negative terminals.
- 4-ohm Load: Wire the two 2-ohm voice coils in series. Connect the positive terminal of coil 1 to the negative terminal of coil 2. Then connect the amplifier's positive output to the remaining positive terminal (coil 2) and the amplifier's negative output to the remaining negative terminal (coil 1).
Use the provided 14 AWG speaker wire and spade terminals to make secure connections. Ensure polarity is correct (+ to + and - to -) between the subwoofer and your amppengikat. Rujuk kepada anda amplifier's manual for specific wiring instructions and impedance compatibility.
