Proper installation is crucial for the performance and safety of your subwoofer. If you are not experienced with car audio installation, it is highly recommended to seek professional assistance.
5.1 Mounting the Subwoofer
The MB1224 subwoofer is designed for installation in a suitable enclosure (not included). Ensure the enclosure is robust and properly sealed for optimal bass response. Secure the subwoofer firmly to the enclosure using appropriate screws, ensuring a tight seal around the mounting flange.

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. Ntuziaka ọrụ
6.1 Oge ezumike
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components to loosen and achieve optimal performance.
6.2 AmpNtọala lifier
Properly setting your 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.

The Memphis Audio MB1224 subwoofer requires minimal maintenance:
- Periodically inspect the subwoofer cone and surround for any signs of damage or wear.
- Hụ na njikọ waya niile dị nchebe ma ghara imebi emebi.
