Having used the AVr100 at work since new, i can tell you it's annoying in the least with its setup. For the best option you will need to wire your front L & R pair, and the sub to the front L & R speaker outputs. Set them to large in the menu and the others to small, option 1 I think. Then you will need to trim the sub's volume and cross-over levels until you get the sound you like. Make sure all bass is sent to the front pair. If you use the all to small and sub on, then you will have to wire the sub to both the front speaker outputs and the sub pre-out. I think is possible with your sub, check your manual. Hope this helps!
