Jon, it wasn't about altering standards it was about making what I had work at the time!
I was running each of four 218 subs on a single bridged CS800C, two 215 midbass each on a bridged CS800C with 6 mains running on a bridged Hybrid setup using two CS1200s as I got more amps I reduced the loads to the amps by adding more amps to fewer speakers.
Eventually I ended up with enough amps to produce 20,000 watts to that system, (was it needed? probably not but I had it available if it were to be needed), but until I added and upgraded my amps i had to make do with what I had.
The setup I have described here was suggested not by another DJ and not by other sound men but by the manufacturers of the gear I was using and that pretty much says it all!
