Not with an iPod dock connection on, unfortunately - the iChord has a 3.5mm stereo jack to connect to the iPod's headphone socket.
The OP's best bet is one of the universal docks made by all the major brands, starting with a budget Cambridge Audio one at around £20 IIRC, and going up through models from the likes of Onkyo, Denon, Marantz, NAD, Pioneer, Yamaha, Arcam and so on. These have stereo analogue outputs, and can be connected to any amp's stereo line inputs. Most also come with a power supply, allowing them to charge the 'Pod while docked; some also have a video output to allow the iPod display to be transmitted to a TV.
I think Apple makes one, too...
