There are a few ways to connect your home theater system to an amplifier. One way is to use a digital audio cable. This type of cable has RCA connectors on either end. You can also use an HDMI cable to connect your devices. An HDMI cable has a male connector on one end and a female connector on the other end. It's also possible to use component video cables or composite video cables. Component video cables have three RCA connectors--one for red, one for green, and one for blue. Composite video cables have only one RCA connector, which is yellow.

When setting up a home theater system, there are three things you need to connect: the TV, the receiver (amplifier), and the speakers. To connect the TV to the receiver/amplifier, use an HDMI cable. Plug one end of the HDMI cable into the HDMI port on the back of your TV and plug the other end of the cable into an HDMI port on the back of your receiver/amplifier. To connect your speakers, use speaker cables. Plug one end of a speaker cable into a speaker jack on the back of your receiver/amplifier and plug the other end of the cable into a speaker. Repeat this process for each speaker.
