I have 4 of them, running my active system. For now they are in cardboard boxes (
) with some heatsinks but I hope to put them in better boxes soon.
Why do you want to run them bridged? You will loose some damping factor (not sure this is an issue though) and only gain some voltage capability, no current capability.
If you really wants to run (2) ncores per speakers you would probably be better off with doing a passive dual amplification (and maybe going full active one day), with only one powersupply. But even then, Bruno Putzeys has stated that running dual wires (right up to the module terminal!) with a single module would already give most of the advantages of a dual amp, thanks to the very high damping factor.
