Connexions d'alimentació
- +12V (BATT): Connect directly to the positive terminal of the vehicle's battery using an appropriate gauge power cable (e.g., 8-gauge AMP KIT). Install an inline fuse (not included) within 18 inches of the battery.
- GND (terra): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection.
- REM (encesa remota): Connect to the remote turn-on output of your head unit or a switched 12V source.

Input Connections (RCA or High-Level)
The MM500.4V supports both RCA (low-level) and high-level inputs.
- Entrada RCA: Connecteu els cables RCA des del pre-emissor de la unitat principalamp sortides al amplifier's RCA input jacks (FR INPUT, RR INPUT).
- Entrada d'alt nivell: If your head unit does not have RCA outputs, use the provided high-level input harness. Connect the speaker wires from your head unit directly to the corresponding wires on the high-level input harness.

Connexions d'altaveus
Connecteu els vostres altaveus al amplifier's speaker output harness. Observe correct polarity (+ to + and - to -) for each speaker. The amplifier supports 4-channel stereo operation or 2-channel bridged operation.
- 4-Channel Stereo: Connect one speaker to each of the four output channels (Front Left, Front Right, Rear Left, Rear Right).
- 2-Channel Bridged: For higher power output to two speakers (e.g., subwoofers), bridge two channels. Refer to the wiring diagram on the amplifier's rear panel for specific bridging instructions.

Instruccions de funcionament
Once installed, follow these steps to configure and operate your ampmés viu.
Encesa inicial
- Després de fer totes les connexions, torneu a connectar la bateria del vehicle.
