2. Varnostne informacije
Pomembni varnostni ukrepi:
- Preden začnete z električnimi deli, vedno odklopite negativni pol akumulatorja vozila.
- Prepričajte se, da so vse žice pravilno napeljane in pritrjene, da preprečite preščipnitev ali poškodbe.
- Za napajalne in ozemljitvene priključke uporabite ožičenje ustreznega premera, kot je določeno.
- Install the subwoofer in a secure location to prevent it from shifting during vehicle movement.
- Izogibajte se izpostavljanju enote vlagi ali ekstremnim temperaturam.
- Ne poskušajte sami odpirati ali popravljati enote. Vsa servisna dela prepustite usposobljenemu osebju.
- Prolonged exposure to high sound pressure levels can cause permanent hearing damage.

5. Nastavitev in namestitev
Pravilna namestitev je ključnega pomena za optimalno delovanje in varnost. Če ste glede katerega koli dela postopka namestitve negotovi, se posvetujte s profesionalnim monterjem avtomobilskih avdio sistemov.
5.1 Mesto pritrditve
Choose a secure and dry location for the subwoofer enclosure, such as the trunk or behind the seats in a truck. Ensure there is adequate ventilation around the amplifier section to prevent overheating. The shallow design of the SB12A is ideal for tight spaces.

5.2 Žične povezave
Glejte na amplifier control panel diagram for correct wiring. Ensure all connections are tight and secure.
Slika: Podrobna view od amplifier control panel. This panel includes connections for power (GND, REM, +12V), fuse, high-level speaker inputs, RCA inputs, and RCA outputs, along with adjustment controls.
- Napajalni priključek (+12V): Connect an 8-gauge power cable directly from the vehicle's positive battery terminal to the "+12V" terminal on the amplifier. Install an appropriate fuse (30A) within 18 inches (45 cm) of the battery.
- Ozemljitvena povezava (GND): Connect an 8-gauge ground cable from the "GND" terminal on the amplifier to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- Daljinski vklop (REM): Connect a remote turn-on wire from your head unit's remote output to the "REM" terminal on the ampvztrajnik. Ta žica obrne ampvklop in izklop sistema za odpravljanje težav z glavno enoto.
- Avdio vhod:
- Nizkonapetostni vhod (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or rear pre-out to the "INPUT" RCA jacks on the amplifier.
- Visokonivojski vhod (nivo zvočnika): If your head unit does not have RCA pre-outs, use the supplied high-level input harness. Connect the speaker wires from your head unit's rear speakers to the corresponding inputs on the harness, then plug the harness into the "SPK IN" connector on the amplifier.
- Daljinski upravljalnik nizkih tonov: Plug the remote bass control knob into the designated port on the amplifier. Mount the knob in a convenient location for easy access.

Ko je nameščen, prilagodite ampnastavitve lifierja za optimalno zvočno delovanje.
6.1 Ampkrmilniki za dvigalo
- DOBITE: This control matches the input sensitivity of the amplifier to the output of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
- LPF (nizkoprepustni filter): Adjusts the upper frequency limit of the subwoofer. Typically set between 50Hz and 120Hz. Frequencies above this setting will be filtered out.
- BASS BOOST: Increases the bass output at 50Hz. Use sparingly to avoid distortion and potential damage. Adjustable from 0-6 dB.
- FAZA: Allows you to adjust the phase of the subwoofer output (0° or 180°) to match the phase of your other speakers. Experiment with both settings to find the one that provides the most coherent bass response.
- DALJINSKO: Connects the wired remote bass level control.
