To connect a powered subwoofer and four speakers to the Lanzar EV424 car power amplifier using the line out RCA jacks, follow these steps:
1. Connect the RCA cables from the subwoofer's line-level input to the line out RCA jacks on the EV424 amplifier. This will send the audio signal from the amplifier to the subwoofer.
2. Connect the speakers to the amplifier's speaker terminals. Make sure to match the positive (+) and negative (-) terminals on the amplifier with the corresponding terminals on the speakers.
3. Set the crossover mode selector on the amplifier to the desired mode. If you want to send low-frequency signals to the subwoofer and high-frequency signals to the speakers, select the low pass mode. If you want to send only high-frequency signals to the speakers, select the high pass mode.
4. Adjust the variable low pass filter and variable high pass filter controls on the amplifier to set the desired frequency range for the subwoofer and speakers, respectively. The range for the low pass filter is 50Hz to 500Hz, and the range for the high pass filter is also 50Hz to 500Hz.
5. Fine-tune the system by adjusting the level controls, phase shift control, and variable bass boost control on the amplifier to achieve the desired sound quality and balance between the subwoofer and speakers.
Please refer to the owner's manual for more detailed instructions and diagrams on how to connect and configure the amplifier for your specific setup.
