5. Instalasi
Proper installation is crucial for optimal performance and safety. If you are not comfortable with electrical wiring, seek professional assistance.
5.1 Pemasangan Amppengangkat
- Choose a dry, stable location away from heat sources and direct sunlight.
- Pastikan ventilasi yang memadai di sekitar amppengangkat.
- Pasang dengan aman amplifier using the provided hardware to prevent movement during vehicle operation.
5.2 Koneksi Kabel
Sebelum melakukan penyambungan apa pun, lepaskan terminal negatif baterai kendaraan.
- Kabel tenaga: Connect the 8-gauge power cable (from RWK82 kit) directly to the positive terminal of the vehicle's battery. Install the fuse holder within 18 inches (45 cm) of the battery.
- Pemasangan Sekring: Masukkan sebuah Sekering 20A into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
- Kabel tanah: Connect the 8-gauge ground wire (from RWK82 kit) from the amplifier to a clean, solid metal point on the vehicle chassis. The ground point should be free of paint and corrosion.
- Kabel Pengaktifan Jarak Jauh: Connect the 18-gauge blue remote wire (from RWK82 kit) from the amplifier to the remote turn-on output of your head unit. If your head unit lacks a remote output, the KEY2004 can use DC offset sensing or audio signal sensing for turn-on.
- Sinyal Input:
- RCA (Low-Level) Input: Use the twisted pair RCA cables (from RWK82 kit) to connect the amplifier's RCA inputs to the RCA outputs of your head unit.
- Speaker Level (High-Level) Input: If your head unit does not have RCA outputs, connect the speaker wires from your head unit directly to the amplifier's high-level input harness.
- Kabel Pembicara: Connect the 16-gauge clear speaker wires (from RWK82 kit) from the amplifier's speaker outputs to your vehicle's speakers. Ensure correct polarity (+ to + and – to –).
