You just need to make sure the output level and connection format of the Mac's headphone socket is compatible with the input Level and connection format of the subwoofer.
I can't help you with that as you've not provided any information about the sunwoofer. Are you sure the sub's input is line level?
I tried it with RCA cable to the headphone jack but just got the faint sound from the subwoofer at the highest volume.
The headphone socket is stereo and an RCA plug is mono... Or was it a dual-RCA cable?
Of course, a sub only reproduces the lowest octave, so you'd need some material that had some decent low end content...
