cd unit w/ sub woofer drive capability
hi guys..i just got a CD head unit with "subwoofer drive capability"..what does that actually mean? could i install a non-amplified subwoofer straight to it?

I wonder if you got a Pioneer MOSFET 50 head unit? If so, they can drive a sub-but never as good as an external amp. The technology is getting much better and I have been some what impressed. I guess something is better than nothing. However if you have the money and you like some real bass don't even bother with it.
Oh yeah the pioneer is 50 W peak and about 22 W RMW and can handle a 2 ohm stereo load but don't try to bridge the rear channels because it can't handle that.

Depends on the impedence of the sub and how many voice coils, etc. A 4 ohm single voice coil sub will only get 22 watts RMS
4 ohm dual will get 22 watts to each coil or 44 watts RMS
Best possible solution is to run 2 dual voice subs and get 44 watts to each sub. I would also run the subs in a ported or bandpass box to take advantage of increased effiency of the subs with a port. That is also my reference point for saying that it wasn't that bad of a setup ... once again for non external amp setup.

If you run a ported or bandpass setup with that wimpy amp, put a low-pass filter or use a cross-over. Uncontrolled excursion below Fs will sayonara your sub and/or amp.

No problem ....
on to what hedgehod said: The pioneer has a built in x-over and you can configure it to only send sub frequencies to the rear channel. (Which should be done and is part of the setup for doing this.)
The other thing he mentioned is a subsonic filter which can be important depending on your tuning frequency and the power delievered below it. However with such little power (relative) and so few bass notes (below 30 Hz) actually recorded in music a subsonic filter is probably just not needed here.
