iPod has a 3.5 mm headphone jack you can use to connect to a home or car stereo using third-party stereo adapters. Note: Compatible devices must be self-powered.

Connecting to a home stereo
For most home stereo systems, connect iPod to your amplifier’s sound input using a 3.5 mm mini stereo to RCA adapter cable.

Adjust the volume on iPod to less than half to prevent overdriving your amplifier. Adjust the listening volume using your stereo’s controls.

Note: Depending on your stereo, iPod may need to be set higher than half in order to get a proper volume through external speakers.
Connecting to a car stereo
Use an extension cable with 3.5 mm stereo connectors on each end to connect iPod to your car stereo system’s aux input, or use a cassette adapter if your car stereo doesn’t have a sound input jack. Either of these items can be purchased at stores that sell car stereo accessories.

iPod models that include a dock connector may be able to connect to some car stereos with a special adapter.
