I have a Pioneer VSX-5300 reciever and was looking on the back to see if it had a specific place to hook up a sub but it doesn't. I am looking at getting a $500 sub and am wondering if the sound will still be seperated with the sub getting the lower frequecies and my regular speakers getting the rest? I do not want to make the mistake of getting a sub and then realizing I can't hook it up to my reciever.
