I am not a expert , some guy here a pretty good here, I can not even tell, I try both and didn't see enough improvement to stick with the bi-amp, the best improvement I did with m80 was when I try with a amplifier (outlaw mono block)

Alright. I have always heard that doubling the watts to the speakers only raises its max output by one db, so I never really cared all that much about power to the speakers Lately tho I keep hearing about "headroom". Can't say I really know what people are talking about with that, but I figured if a 145w gave you more headroom than 100w, wouldn't bi-amping give you more, and wouldn't that be better?

This doesn't give you any more headroom, and doesn't double the power. There are several good discussions of the math on this if you do a search on biamping. Look for posts by ClubNeon.

Ah I can't believe you regulars just don't scream when people like me ask questions that have been asked a thousand times. Poor Johnk. I just read like 20 different posts of him explaining bridging and bi-amping, for people like me. From now on I will search the forums before asking questions. Thanks everyone.

Steve, we can always make it 21. No, you can't bi-amp with a receiver, despite the terminology that some of the manufacturers shovel out. A receiver has only one amplifier with several channels of output transistors to distribute that power. Distributing the power through two sets of output transistors rather than one doesn't double the power as some imagine and can't increase the power available from the one power supply section in any amount.

Enjoy the music, not the equipment.

lol I'm sure youve done it more than 21. I got it now. learned a lot tonight. Just learning ohms law answers a bunch of questions I had in my mind. Just in case any other newbs are reading this - search the forums first. I didn't even notice that you could before tonight. Anywho thanks again everybody.

as long as your receiver is rated for the 4ohm load and you have an extra set of speaker cables, then go for it. your manual will tell you how to do it; it will be in the speaker setup or type in the receiver menu. you will be giving up a pair of speaker outputs, usually the surround backs but with this new receiver you may be able to choose the height or width channels. you will either like what you hear or you won't or you won't hear anything but as long as your not hurting any of your gear, it's your stuff, don't let folks talk you out of it or try to make you feel bad for wanting to try it.

if you do try it, let us know what you think, you have to either like it or not, no one else!

No. Your manual will clearly state not to bi-amp 4Omh speakers.
