If I were to connect a JBL pb-12 sub using the speaker wire inputs would it be the same as connecting it using the mono wire to the receiver? I don't really have money for a half way decent cable right now so I am wondering if connecting it this way would be the same.

Thanks

Jamie,
The short answer: It depends on your equipment and room. IF your receiver has speaker level binding posts for the sub, then you might be able to do this easily.
I would simply connect the sub via the LFE connection (RCA style jack) from the AV REC to the input(s) on the back of the sub. Unless your mains are big honkin towers that can play down to 20hz, set ALL speakers to small and sub = yes in the receiver. I don't think I'm the only one who would tell you to not stress too much over the quality of this cable. Just get a decent, shielded cable from rat shack. It's simpler and more efficient.
I experimented with the speaker level connection extensively and it did not give as good a response. Your results may vary, but it's certainly more of a hassel to do it correctly. Many people do this to use their sub's variable x-over. But, to do this, you would likely have to connect the sub to the main speakers binding posts, then run your main speakers off the sub and set the mains to large and sub = no then use the sub's x-over in order to get true DD and LFE material. It's more complicated than it's worth for most people, and the benefit is oftentimes marginal, if at all with this setup.
