In general, you can connect it in two ways: Either you can supply a line in signal via phono as is usually used between a preamplifier and power amplifier. Use the red and white input connectors for this. Or, you can insert the sub between your amplifier and your speakers thereby tapping into the amplified signal. Use the red and black screw connectors for this.

Once connected, you can adjust the volume of the sub to match that of your main speakers and decide the cut-over frequency (where the sub starts working) using the knobs.

Your receiver has dedicated subwoofer phono outputs, and you are probably best of using those with the red and white phono inputs on the sub. You may then be able to handle the necessary volume adjustments etc. from the Sony and that may then be the best way.
