Connexions de cablejat
Ensure all connections are secure and properly insulated. The amplifier features sealed connections for enhanced element resistance.
- Connexió d'alimentació: Connect the positive (+) power wire to the vehicle's battery (or power distribution block) via an appropriate fuse (not included). The recommended amp kit is 8GKIT. Connect the negative (-) ground wire to a clean, unpainted metal surface on the vehicle chassis.
- Encès remot: Connect the remote turn-on wire from your head unit to the amplifier's remote input.
- Entrada d'àudio: Use either the high-level (speaker level) inputs or low-level (RCA) inputs from your head unit. Ensure correct polarity for all connections.
- Sortida de l'altaveu: Connecteu el(s) subwoofer(s) al amplifier's speaker output terminals. Observe correct polarity.

Funcionament
Once properly installed, your MXA300.1 amplifier is ready for operation. The amplifier features a subsonic filter to optimize subwoofer performance.
- Encès/apagat: El amplifier will power on automatically when it receives a signal from the remote turn-on wire from your head unit. It will power off when the head unit is turned off.
- Ajust de guany: Ajusteu el control de guany per coincidir amb el volum de sortidatage of your head unit. Start with the gain at minimum and slowly increase it until you achieve clear, undistorted sound at your desired volume level.
- Filtre subsònic: The built-in subsonic filter helps protect your subwoofer by filtering out extremely low frequencies that are inaudible and can cause damage. This filter is pre-set for optimal performance.
