5.2 Wiring and Impedance Selection
The MB1224 features selectable impedance (2 Ohm or 4 Ohm) using the included jumper cables. This allows you to configure the subwoofer to match your amplifier's capabilities. Always ensure your amplifier is stable at the selected impedance.
5.2.1 4 Ohm Wiring Configuration
To configure the subwoofer for a 4 Ohm load, connect the included jumper cable between the two positive terminals and another jumper cable between the two negative terminals. Then, connect your amplifier's positive output to one of the positive terminals and the amplifier's negative output to one of the negative terminals. Refer to Figure 3 for a visual guide.

5.2.2 2 Ohm Wiring Configuration
To configure the subwoofer for a 2 Ohm load, connect the included jumper cable from the positive terminal of one voice coil to the negative terminal of the other voice coil. Then, connect your amplifier's positive output to the remaining positive terminal and the amplifier's negative output to the remaining negative terminal. Refer to Figure 4 for a visual guide.

6. Návod k obsluze
6.1 Období záběhu
Před použitím subwooferu na vysokou hlasitost nechte jeho záběhovou dobu přibližně 10–20 hodin běžného poslechu. To umožní uvolnění závěsných prvků a dosažení optimálního výkonu.
6.2 AmpNastavení filtru
Správné nastavení vašeho amplifier's gain, crossover, and bass boost is critical. Start with the gain at its lowest setting and slowly increase it until you achieve the desired volume without distortion. Set the low-pass filter (LPF) on your amplifier to prevent high frequencies from reaching the subwoofer, typically between 80Hz and 120Hz. Avoid excessive bass boost, as this can lead to distortion and potential damage.
7. Údržba
The Memphis Audio MB1224 subwoofer requires minimal maintenance:
- Periodically inspect the subwoofer cone and surround for any signs of damage or wear.
- Ujistěte se, že všechna kabelová spojení jsou bezpečná a bez koroze.
- Clean the subwoofer's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the subwoofer free from dust and debris, especially if it is not enclosed.
8. Řešení problémů
Pokud máte problémy se subwooferem, podívejte se na následující běžné problémy a jejich řešení:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Žádný zvuk ze subwooferu | Žádná síla amplifier, incorrect wiring, amplifier in protect mode, low input signal. | Kontrola amplifier power and ground connections. Verify all speaker wires are correctly connected and secure. Check amplifier fuses. Ensure head unit is sending a signal. |
| Zkreslený nebo nejasný zvuk | Amplifier gain set too high, incorrect crossover settings, damaged subwoofer, poor enclosure. | Snížit amplifier gain. Adjust LPF settings. Inspect subwoofer cone and surround for damage. Ensure enclosure is sealed and properly sized. |
| Subwoofer se občas vypínal | Loose wiring connections, amplifier overheating, impedance mismatch. | Check all wiring connections for tightness. Ensure amplifier has adequate ventilation. Verify subwoofer impedance matches ampstabilní provozní dosah zařízení Liferier. |
| Subwoofer is too quiet | Amplifier gain too low, incorrect phase setting, low input signal. | Zvýšení amplifier gain gradually. Check phase setting on amplifier or head unit. Ensure head unit volume is adequate. |
If the problem persists after attempting these solutions, contact Memphis Audio customer support or a qualified car audio technician.
