The slim design allows for flexible mounting options, such as under a seat or in the trunk. Ensure adequate air circulation around the unit for proper heat dissipation.

• Select a suitable location that does not obstruct vehicle operation or safety.
• Use the provided mounting iron sheets and screws to secure the subwoofer.

5.2. Power Connections

• Connect the GND (Ground) terminal to the closest point on the vehicle chassis. Ensure the ground wire is less than 39" (100 cm) in length.
• Connect the +12V terminal to the positive terminal of the car battery via the provided fuse holder.
• Connect the REM (Remote Turn-On) terminal to the remote output of your head unit. If your head unit does not have a remote output, you can use the Auto Power On feature (if available) or connect to an accessory wire that turns on with the ignition.

5.3. Signal Input (Low-Level RCA or High-Level Speaker Inputs)

Choose the appropriate input method based on your head unit's capabilities. Do not use both high-level and low-level inputs simultaneously.

• Low-Level RCA Input: Preferred for best audio performance. Connect RCA cables from your head unit's RCA outputs to the subwoofer's Low-Level inputs.
• High-Level Speaker Input: Use this if your head unit lacks RCA outputs. Connect the speaker wires from your head unit to the subwoofer's High-Level inputs. The provided DHLC (Delayed High-to-Low Signal Converter) can be used for this purpose.
