Try it and see. If you get very low sound (quite likely, considering the
output levels on the TV tuner card probably aren't much more than a couple
of watts), you'll need to put an amp between the card and the speakers.
Most boom-box speakers are rated for about 10 watts or so.
Make sure you match impedance too. Most Macs are rated at 8 ohms, IIRC,
and the boom box speakers *probably* are, but they could be 4 ohm.
