Trust me I know exactly what you're going through. You got these 2 sets of binding posts on each speaker and just cause their there you want to use them. I went through it as well and the response I kept getting was it's not worth it. I actually went and got a 2 ch power amp with gain thinking I could use it on just the mains woofers to have louder bass. When I hooked it up I was quite dissapointed to find that it wouldn't play louder than the reciver even though it had gain. Only after I sold my center and satelites and went 2ch that I figured out that I could use my reciever as a 4ch stereo amp. If you want to play around with bi-amping and get a taste of it take 2 of your satelite channels and hook them up to the woofer posts on your fronts. Then go into the reciever and turn thoese 2 channels up and leave the rest alone. Then listen to some music on 7ch stereo and see hows its different. Though with having a sub I doubt you'll notice it. The reason I did this was to get more bass volume cause I don't have a sub. When I do get one which should be very soon I'll go back to full range. It's definately a poor mans bi-amping but it's fun to play around with just as it's fun to try different speaker placements other equipment and such.
