Adding an active sub (when my amp has no sub pre-out)

Speaker Asylum

General speaker questions for audio and home theater.

210.9.226.210

I have a passive sub connected to a 6 channel amp with no sub pre-out. Can I connect an active sub in any way? Crutchfield has this on their site:
Q: Can I hook up a powered subwoofer if my receiver doesn't have a subwoofer output?
A: Absolutely. Almost all powered subwoofers have speaker-level connections for use with virtually any receiver. Just run one set of speaker cables from your receiver's main left and right speaker outputs to the subwoofer, then another from the subwoofer to your main left and right speakers (you'll need an extra pair of speaker cables).
Is this true? I would have thought that the l/r signal from my receiver is only a signal for those speakers, and wouldn't have low frequency bass. Any help would be appreciated :-)
