Wiring a powered subwoofer

by rph206 / July 25, 2008 5:35 AM PDT

Hi, I'm trying to figure out the wiring of the house I just moved into. There are 2 in-ceiling speakers wired through the walls. There is also a single-pair speaker wire wired through the walls for a subwoofer (unfortunately stapled behind the walls so it's very tough to pull another wire). Anybody have an idea regarding what the anticipated setup was? Is there a way to set up a powered subwoofer using a single-pair speaker wire? I'm baffled, but I'm sure there are much more experienced folks out there who might get it.

The sub has all sorts of inputs, but the wire is a speaker wire and the receiver does not have a single-wire sub output, only 2 sets of L and R speaker posts.

does not have a dedicated sub-woofer out you cannot use a powered sub-woofer. A powered sub wants a preamp input which is driven up to volume. You'll need a standard non-powered speaker. If you connect the powered L/R outputs to the powered sub you'll blow it out.
