ຂັ້ນຕອນການຕິດຕັ້ງ

1. ການກະກຽມດ້ານການຕິດຕັ້ງ: Cut an 11-inch diameter hole in the chosen mounting surface. Ensure there is at least 5.5 inches of clear depth behind the mounting surface.
2. Install Back Gasket: Place the provided back gasket around the mounting flange of the subwoofer. This helps create a seal and prevents vibrations.
3. ການເຊື່ອມຕໍ່ສາຍ: Connect the subwoofer wires to your amplifier. The 45KMF122 has a 2-Ohm voice coil. Ensure your amplifier is stable at 2 Ohms. Use marine-grade wiring and ensure all connections are properly crimped, soldered, and sealed to prevent corrosion.
4. Mount Subwoofer: Carefully place the subwoofer into the prepared hole. Align the mounting holes.
5. Subwoofer ທີ່ປອດໄພ: Use the provided mounting screws and clips to secure the subwoofer to the mounting surface. Tighten screws evenly to avoid warping the frame. Do not overtighten.
6. Protective Terminal Cap: Ensure the protective terminal cap is securely in place over the wiring terminals to prevent moisture ingress and short circuits.

1. ເປີດ: Ensure your marine audio system, including the amplifier connected to the subwoofer, is powered on.
2. ປັບ Ampການ​ຕັ້ງ​ຄ່າ lifier​: Set the gain, crossover frequency, and phase settings on your amplifier according to the subwoofer's specifications and your listening preferences. A typical low-pass crossover frequency for a subwoofer is between 80 Hz and 120 Hz.
3. ການຄວບຄຸມລະດັບສຽງ: Adjust the volume from your head unit. Avoid excessive volume levels that cause audible distortion, as this can damage the subwoofer.
4. ໄລ​ຍະ​ເວ​ລາ​ທີ່​ແຕກ​ຕ່າງ​ກັນ​: Allow a break-in period of several hours of moderate use before operating the subwoofer at maximum output. This allows the suspension components to loosen and perform optimally.

The subwoofer is designed for mono audio output.
