Follow these steps for secure and correct wiring:
- Power Wire (+12V): Connect the 17FT Translucent Blue Power Wire from the vehicle's positive battery terminal (via the Mini-ANL/AFS Fuseholder & Fuse, installed within 18 inches of the battery) to the +12V terminal on the amplifier. Ensure a secure, crimped connection.
- Ground Wire (GND): Connect the 3FT Translucent Silver Ground Wire from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid, low-resistance connection.
- Remote Turn-on Wire (REM): Connect the 16FT Blue Remote Turn-on Wire from the REM terminal on the amplifier to the remote output of your head unit or other switched 12V source. This wire turns the ampFa'aola ma tape le eletise (lighter) i lau head unit.
- RCA Ulufale: Connect the 17FT Translucent Blue Twisted Pair RCA interconnects from the RCA output of your head unit to the INPUT RCA terminals (L/R) on the amplifier. For bridged input, use the BRIDGE IN RCA terminal.
- Galuega Fa'atino: Connect your subwoofer(s) to the MONO OUTPUT MIN 1 Ohm terminals on the amplifier using the 20FT Translucent Speaker Wire. Observe correct polarity (+ to + and - to -). Ensure the total impedance of your subwoofer(s) is 1 Ohm or higher.
- Remote Subwoofer Level Control: Plug the included remote bass knob into the REMOTE port on the ampola
5.3 Fa'amauina
Choose a mounting location that provides adequate ventilation and is secure. Avoid mounting the amplifier directly to carpet or in enclosed spaces without airflow. Use the provided mounting hardware to firmly attach the amplifier to a solid surface in your vehicle.

A uma ona fa'apipi'i, fetu'una'i le ampfa'atulagaga o le leo mo le fa'atinoga sili ona lelei o le leo.
6.1 Fetuuna'iga o Pulega
- GAIN (Input Level): O lenei pule e fetaui ma le amplifier's input sensitivity to the output of your head unit. Start with the gain at minimum (fully counter-clockwise). Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the gain until you hear distortion, then back off slightly.
- LPF (Fili'iliga Maulalo): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust this knob (40Hz-180Hz) to blend the subwoofer's output with your main speakers. A common starting point is 80Hz.
- SUBSONIC: This high-pass filter removes extremely low frequencies that are below the audible range or harmful to your subwoofer. Set it to OFF or 50Hz, depending on your subwoofer's capabilities and enclosure tuning.
- FREQ (Bass EQ Frequency): This knob (30Hz/80Hz) selects the center frequency for the Bass BOOST.
- BOOST (Bass EQ Level): This control (0dB/12dB) increases the output at the selected FREQ. Use sparingly to avoid distortion and potential damage to your subwoofer.
6.2 Remote Subwoofer Level Control
The included remote level control allows you to conveniently adjust the subwoofer output level from your driving position. This control only adjusts the output level and does not affect the ample setiina o le fa'aopoopoga a le lifier.
