QSC PLX 3402 in 4 ohm bridge

Mate of mine called me today asking if I know anyone selling PLX 3402.

Reason:He bridged one across couple of 1850 subs, and rated it as good as many torroidials he as heard.

He says the older version is best for some reason.

Anyone else done this with this amp ?

I have a couple of the newer ones that I use in my main rack. The only problem I have with them is that they run very hot.
It has not been an issue during the winter but I am keeping a close eye on them as the weather warms up (hopefully). Great amps though.
They will be going in my spare rack soon when I replace them with some Matrix SMPS models.
