Konnessjonijiet tal-Wiring
Ensure all connections are secure and properly insulated. The amplifier features sealed connections for enhanced element resistance.
- Konnessjoni tal-Enerġija: 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.
- Tixgħel mill-bogħod: Qabbad il-wajer tar-rotob mixgħul mill-unità ewlenija tiegħek mal- ampL-input remot tal-lifer.
- Input Awdjo: Use either the high-level (speaker level) inputs or low-level (RCA) inputs from your head unit. Ensure correct polarity for all connections.
- Riżultat tal-Kelliem: Qabbad is-subwoofer(s) tiegħek mal- amplifier's speaker output terminals. Observe correct polarity.

Operazzjoni
Once properly installed, your MXA300.1 amplifier is ready for operation. The amplifier features a subsonic filter to optimize subwoofer performance.
- Power On/Off: Il- 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.
- Aġġustament tal-gwadann: Adjust the gain control to match the output voltage 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.
- Filtru Subsoniku: 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.
