1200W Powered Car Truck Sub: Slim Under-Seat 10" Subwoofer w/ Amp Kit Speaker


**⚠️ IMPORTANT: Please Read Before Use / Troubleshooting Guide**

**Quick Start Checklist:**

1. **Power Connection**: Ensure the red wire (+) is connected to battery positive (+) and black wire (-) to battery negative/ground (-). Reversed polarity will prevent the unit from powering on.

2. **Remote Turn-On**: The blue/white wire must be connected to your head unit's remote turn-on lead (or ACC power). Without this signal, the amplifier will not activate.

3. **RCA/High-Level Input**: Connect either RCA cables (low-level) from your head unit, OR use the high-level input wires if your stereo lacks RCA outputs. Do not connect both simultaneously.

4. **Fuse Check**: Verify the 25A fuse on the power cable is intact and properly seated.
