I just bought a JBL PB12 and am wondering what is the best way to hook it up? DO I need to go buy some cables for it? I have a Denon 2802 driving it, and also the JBL NSP1 system. (I have just recently aquired these things...I am very excited!!) In any case. It has the posts in teh back and the LFE stuff. Being new to this, what do I need to do? Thank you for your patience with me and thanks for your help!
