Why? There should be no need to do so as they do not (or at least not audible) interfere with eachother. Having any problems with interference?? Synchronising them is supposed to reduce the sound quality so better not do it.

If you need to synchronize them, these are not the better modules to do it, as they are free-running. You'd better choose something synchronous. I bought some coldamps and they have the option. Just in case it helps

you can connect a series r-c from one amp to the next...
try about 0,1uf + 10 ohm
this syncs osz frequ at low levels.
you got idle tones or what ?
