You can certainly use any subwoofer that has its own amplifier with your surround sound system, if the only signal you send it is the sub line out from the receiver. The power rating of the subwoofer gives you a good indication of the volume balance that you can expect.

Yes. 7.2 is actually a misnomer, as there isn't 2 sub channels, just two outputs for dual subs. It should actually be called 7.1. There are very few 7.1 mixes around.

To connect a powered subwoofer to a surround sound system using only black and red speaker wires, you can use a speaker-level input method. Connect the positive (red) wire from the sub channel to the positive terminal of the subwoofer and the negative (black) wire to the negative terminal. If your subwoofer has high-level inputs, you can also connect the speaker wires from the surround receiver directly to the subwoofer's high-level inputs, allowing it to receive the audio signal and amplify it. Ensure that all connections are secure before powering on the system.
To connect a surround sound system to your TV, you'll typically use an HDMI cable, which supports high-quality audio and video. If your TV and surround sound system both have HDMI ARC (Audio Return Channel) ports, use that for easy connection. Alternatively, you can use optical audio cables or RCA cables if HDMI isn't available. Ensure to check the specific audio outputs on your TV and inputs on your surround sound system for compatibility.
