• LAUTSPRECHER: Output terminals for connecting your subwoofer(s).
• POWER (+12V): Connects to the positive terminal of the vehicle's battery.
• REM (Fernbedienung): Connects to the remote turn-on output of your head unit.
• GND (Masse): Connects to a solid chassis ground point in the vehicle.

5. Installation

5.1 Montage der Ampschwerer

Wählen Sie einen trockenen, gut belüfteten und sicheren Montageort. Stellen Sie sicher, dass ausreichend Luftzirkulation um das Gerät herum gewährleistet ist. amplifier to prevent overheating. The amplifier can be mounted horizontally or vertically. Use the provided mounting screws to secure the amplifier to a solid surface in your vehicle.

5.2 Kabelverbindungen

Proper wiring is crucial for optimal performance and safety. Refer to Figure 3 for terminal locations.

1. Stromanschluss (+12V): Run a heavy-gauge power cable (e.g., 4-gauge or larger) directly from the vehicle's positive battery terminal to the amplifier's +12V terminal. Install an in-line fuse holder with an appropriate fuse (not included) within 18 inches (45 cm) of the battery.
2. Masseanschluss (GND): Verlegen Sie ein dickes Erdungskabel (gleicher Querschnitt wie das Stromkabel) von der amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection by scraping away any paint or rust. The ground cable should be as short as possible, ideally less than 3 feet (1 meter).
3. Remote Turn-On Connection (REM): Connect a smaller gauge wire (e.g., 18-gauge) from the amplifier's REM terminal to the remote turn-on output of your head unit. This wire tells the amplifier to turn on when your head unit is active.
4. RCA Input Connection: Connect RCA cables from the pre-out outputs of your head unit to the INPUT RCA jacks on the ampschwerer.
5. Lautsprecheranschluss: Connect your subwoofer(s) to the SPEAKER output terminals. Ensure correct polarity (+ to + and - to -). The amplifier is stable down to 1 Ohm. Consult your subwoofer's specifications for proper wiring configurations to achieve the desired impedance.
6. Remote-Bassregler: Plug the remote bass knob cable into the REMOTE port on the amplifier and mount the knob in a convenient location for adjustment.

6. Bedienung

6.1 Erstes Einschalten

After all connections are made and verified, reconnect the vehicle's battery. Turn on your head unit. The POWER LED on the amplifier should illuminate. If the PROTECT LED illuminates, refer to the Troubleshooting section.

6.2 Einstellen Amplifier-Einstellungen

Adjust these settings carefully to optimize sound quality and prevent damage to your speakers.

• DAZUGEWINNEN: Start with the GAIN control at minimum. Play a familiar piece of music at a moderate volume on your head unit. Slowly increase the GAIN until you hear distortion, then back off slightly. This sets the ampDie Eingangsempfindlichkeit des Verstärkers muss mit der Ausgangsempfindlichkeit Ihres Autoradios übereinstimmen.
• LPF (Tiefpassfilter): Adjust the LPF to filter out frequencies above your desired subwoofer range. A common starting point is 80-100 Hz. This ensures only low frequencies are sent to your subwoofer.
• SUBSONIC Filter: This filter removes extremely low frequencies that your subwoofer cannot reproduce efficiently, preventing damage and improving sound quality. Set it slightly below your subwoofer's port tuning frequency or around 25-30 Hz for sealed enclosures.
• BASS BOOST FREQ & BASS BOOST: Use these controls to enhance bass output at a specific frequency. Start with Bass Boost at 0 dB and adjust only if needed. Excessive bass boost can cause distortion and damage.

6.3 Fernbedienung für Bassregler
