A home stereo typically will come with a built-in amplifier for powering the system and driving the speakers. The main reason for connecting an amplifier to the stereo would be to supply additional power for driving larger or additional speakers for a stronger sound. This setup requires a home stereo with audio output jacks for connecting a second tape deck, except the amp will be connected to these jacks instead of a tape deck. Standard stereo audio cables complete the connection.
Unplug the stereo and the amplifier from the electricity.

Connect the two plugs on one end of the audio cable to the left and right output jacks labeled for the tape deck on the home stereo. The red plug connects to the right jack and the white plug goes to the left.
Insert the plugs on the other end into the matching left and right audio inputs on the amplifier. Any unused set of inputs will work–just make a note of the label on the input, such as tape deck, CD, turntable or other component.
Set the component selector on the home stereo to Tape 2 and set the amplifier's component selector to the set of jacks that connect it to the home stereo.
Restore the electricity to the components only after the audio cable is connected.
