If beetz has a stereo with a mini-input then he can buy a really cheap mini(standard head phone input thing) to mini cable and use audio output on that with his speakers.
If beetz doesn't then he can get one of these mini-to-rca cables(what ever works with beetz setup):

assuming beetz speakers have RCA inputs on his speakers.
erbbysam doesn't appreciate having to interpret things in the third person.
