BIAMPING

Its me again - SFrounds, Need help on biamping questions.

Stupid question#1
Why is it that an amp rated at 125 wpc can deliver 400 watts mono, why wouldn't it be 250?

Now for the rest of these questions, lets say I have two of these identical amps, and a pair of speakers that can be biwired.

Hopefully - not as stupid question#2
What is the best way to wire these amps?

(A)Have one amp wired to supply the low frequencies on each of the right and left channel speakers, and one amp wired to supply the high frequencies on each of the left and right channel speakers.(at 125 wpc each)

(B)Have the amps wired mono at 400 wpc with one amp biwired to the right channel speaker and the other amp biwired to the left channel speaker.

(C) none of the above or other recommended option.

Thanks again, (Don't worry I can Take abuse very well)

It looks to me like you have the following options:

1) Run each amp bridged mono, wired in to each speaker.
2) Run each amp stereo, one for highs, one for lows
3) Run each amp stereo, high and low of one speakers in one amp and v.v.

I went through this scenario fairly recently, and there are things to be set for each of the three setups. I preferred using scenario 2, using one amp for left and right mids, the other for left and right bass. It just seemed to create an energy and bass clarity that the other combinations did not.

(I did this with a set of NHT 2.9 speakers I own, and two ML331's I had on loan.)

Hmmm...perhaps an important point to make here... If the speaker just has dual connectors without some sort of shorting bar you can remove, the speakers could be BI-WIRABLE but NOT BI-AMPABLE. I don't know if there are any speakers to which this would apply, but if you have no shorting bars you can remove, be extremely careful! Tying the outputs of two amps together is almost certain cause of serious amp damage...
