I have RM6800 and Onkyo TX-LR552 receiver. Here is my questions. Hope someone could answer them:
1. Subwoofer: I used recommended connections from RM6800 manual (Connect to speaker in on sub) and got wierd sound from sub. I read some comments on this forum and changed to use Sub-out on receiver to left Line-in on sub. Wierd sound was gone, but I got humming sound from sub even the switch was on OFF.

2. I'm using 12 gauge wire, which is very thick and could not fit receiver terminal (spring clips) and speakers (binding). I managed to attach connecter pins on the wire and the pin fits both terminal and speaker. However, on receiver side the pins are next to each other and easy to get touched with each other. I'm afraid they may cause short-circuit. I attached a photo of those pins.

3. Should I set speakers to Large or Small?

4. What's the Xover value should set?

Thanks for the advice.
