I can only direct you on the right way...then you have to ask somebody else because I have no time in these weeks..
Rough solution: connect L and R channels to the inverting pin of a high quality opamp, configured as buffer, then the opamp output to the amp. Virtual earth allows mixing channels without messing source signal.

what if i have a b1 buffer already?
sorry but I made a mistake.
You have to put a high value (eg 50k) resistor before inverting terminal, one each channel....then u have to set a resistor on the feedback or it can goes in buffer configuration.
About B1...don't know, but it would be better a new device for this application.
hope someone else can help you, but this is the way, try googling.

You can create a "line level" output after the power amp. I have a simple schematic somewhere.
Audio magus used to make a SUBLINE accessory to do this for t amps. Google it.
do u still have it? audiomagus is not producing any of those anymore.
Like the Audio Magus product, you simply connect this circuit to the loudspeaker terminals.
An externally hosted image should be here but it was not working when we last tested it.

alright thanks. so i have to make 2 of this to achieve a R and L line level output correct.
Yes.
You wont need long interconnects though!
alright thanks. shall do in a perf board. also wad it means by signal too much?
