Sal,
The WP4 is a wall plate for speaker cable.
There are several ways to connect an Ipod to your speakers though-You will need an amplifier/Receiver to connect between your iPod and speakers unless you are planning to connect to powered speakers. To connect to an amplifier like our AMP120 yoou will need a RCA to MINI cable, (product code OSD-MS-3ft ) That would go into the headphone jack of the Ipod and the RCA would go into the back of the Amp/ Reciever.
