connecting archos to bose stereo

[pugcc]

hi guys!!! I'm new here so be gentle with me!! Looking to buy an S4 Cab with the BOSE stereo, is there a way to connect up my Archos MP4 player by installing a lead to somewhere in the stereo with a 3.5mm plug which connects to the headphone socket? If not I guess Ill have to use a cassette adaptor or radio transmitter.....
