I have a question about bi-amping my Polk Momo MMC 6500 component set. Right now I am powering them with a 2-channel Pioneer amp pushing 125 watts to each. My question is how much power can they handle if I bi-amp them and what are the benefits or downfalls of bi-amping them?
no downfall. benifits are more control. 125 per speaker might be too much even with the gains set to flat.
Id go with 60-75 watts per channel.
Yeah I will get a lower power 4 channel amp if I do bi-amp them. My question was how much rms per channel should I get? I couldn't find ratings anywhere on how much they can handle when bi-amping them.

For one they don't make this amp anymore do they and secondly do you think that would be too much power? The last thing I want to do is blow my components. I love them too much and got them for a great deal on Crutchfield.

Might be. How much? Whats the output of the amp?

here is the link:
Thanks for the link. Thats a bit more than I can spend right at the moment but its still good info. Thanks to everyone who responded.
