I've been loosely looking for a stereo amp or receiver, but I saw a real good deal on an open box 7.1 receiver, so I jumped on it. Its a marantz 6005, the power specs are 7x110w. I know for sure I can run stereo with a L and R channel each feeding 110 watts. My question is, if my speakers have two sets of speaker terminals, aka bi-ampable (I believe it means I can separately power the driver and tweeter), can I connect two L and two R channels, effectively feeding each speaker 220 watts (110 to the driver and 110 to the tweeter)? If yes, what setting would I need on my receiver? Full channel stereo?

If the AVR is designed to allow it (if the manual says so explicitly) then yes, but not with all ch stereo. Read the manual how to do it.

The WPC figure is only rated for 2ch. For 4ch it'll be lower.

In any case it's been said n times it's pointless to do it. Read this.

Audiosceptics accept audio trials using 25 people. A recent Oxford study with over 353,000 patient records from 639 separate clinical trials shows for every 1,000 people taking diclofenac or ibuprofen there would be 3 additional heart attacks, 4 more cases of heart failure and 1 death every year.

As is the case with many 7.1 AVRs, the 6005 has a "bi-amp" configuration setting by connecting the rear surround terminals to the 2nd set of speaker posts on the FL/FR speakers, although as noted above, this type of passive bi-amping is not likely to produce any additional power nor improved audio fidelity.

Oh wow, ok. I was under the impression that this would basically allow me to feed by speakers a lot more juice by biamping, but I guess not. I'll look into it a bit more then. Thanks guys
