It needs to be encoded on the media such as a DVD movie or CD - it should say 7.1 surround recorded. I'm assuming you have all seven speakers and sub-woofer hooked up, too?

your sony channels receiver it says protect bec ther is to much power on the speakers to fix it get les powered speakers then it will work

Why not? People have been known to run them with lesser receivers and sources.

If you're using the terminals for Surround Back (7.1) there is no Speaker B option.

See the notes on page 19 of the manual.

NO! It uses the same amps for a and b channels. and you could short it out if its wirer improperly.

If the speakers themselves work fine, then the problem lies within the amplifier output. The channels can go bad after hard use, they can be repaired but it may well exceed the cost of the amp if it is not just one channel. Also be sure that you are hooking up speakers that are rated for your amplifier by matching the OHM resistance of the amplifier to compatible speakers.
