Setting up monoblocks

Thanks, I am not a huge movie fan so surround is not an issue . Bringing up the ohms is now confusing so I guess I have more reading to do this afternoon. I do know that my speakers are ,

Frequency Response: 43Hz – 20KHz

Suitable Amplifier Power Range: 15-200watts

Impedance: 6 ohms

Sensitivity - Room / Anechoic: 91.5dB/88.5dB

and the amps are .

Rated power: 250 watts into 8 ohms, 20Hz-20kHz, <0.02% THD, 450 watts into 4 ohms, DIN 1 kHz

Dynamic power: 650 watts into 4 ohms, 1100 watts into 1 ohm

Hi Eagleflyerfan,
I had those amps and they satisfied me almost twenty years. They were very good.Enjoy them.
I had them hooked up right mono amp handling front and rear right, and left amp handle left side.
I didn't use a pre.Ran them directly from cdp.The 'A' controlled the front speakers and the 'B' took care of the rear.

Regards,

Thanks Montejay, I have a bad habit of over complicating things. I figured that was the setup, but it was also nice to hear from someone whom actually used the amps.
I still need to figure out the amp impedance to the speaker etc. theory but I should be able to Google that to find out what is going on there.

Thanks again everyone for your help.

Eagle . . . . before you start having anxiety attacks over mixing speaker impedances, etc, first consult your owner's manual. Most amps that have include multiple speaker switching, like yours, will automaticall insert some additional resistance in the output circuit when you choose the "A+B" option, to protect the amp from too small a load impedance.

Nsgarch - I appreciate you taking the time to actually look up the amplifiers and getting to the bottom of the story.

I made the assumption that a monoblock amplifier would be intended to only run a single channel and the use of a rear channel set of speakers would be better using a second amplifier. The ability of the amplifier to run two sets of speakers in an A/B configuration would be perfect for people with two sets of main speakers, but it didn't occur to me that anyone would want to run identical signals to both front and rear speakers.

Wouldn't using a pair of these amplifiers to drive a pair of front and rear speakers be the equilavent of putting a surround receiver on the "all channels stereo" setting? It's can be nice for room filling sound but is certainly not for critical listening.

Your additional research gave the OP more information to work with and that's always a benefit.
