- Pastikeun ventilasi nyukupan di sabudeureun éta amppangagung.
- Aman dipasang dina amplifier using the provided hardware to prevent movement during vehicle operation.
5.2 Sambungan Wiring
Sateuacan ngadamel sambungan naon waé, pegatkeun sambungan terminal batré négatip kendaraan.
- Kawat kakuatan: 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.
- Pamasangan sekering: Lebetkeun a 20A sekering into the fuse holder. The 60A fuse included in the RWK82 kit is too large for the KEY2004 and must be replaced.
- Kawat taneuh: 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 Pangaktipkeun 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: Upami unit sirah anjeun henteu gaduh kaluaran RCA, sambungkeun kabel spiker tina unit sirah anjeun langsung ka amplifier's high-level input harness.
- Kabel Speaker: 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 –).
