1. Is this a powered subwoofer or does it need an amp?
   Powered. The amplifier is built in. You just connect signal and plug it into power.
   
2. How do I connect it to my AV receiver?
   Use the receiver’s Sub Out or LFE output to the sub’s line input, then run your receiver calibration and fine-tune the sub level.
   
3. Where should I place it for the best bass?
   Start near the front wall, slightly off a corner. Corner placement boosts output, mid-wall can sound tighter. Try 2 to 3 spots, small moves can change bass a lot.
