I can see this turning into a messy thread before it's over...
But to answer your question I personally have a 4-channel and a monoblock.
Both are Kenwood.
The multichannel is from their Performance Standard line (KAC-PS500F)....the predecessors to today's eXcelon lineup and the monoblock is an eXcelon KAC-X401M (though I am looking into getting their new KAC-X1R if I can scrounge up the $$$)
I have 2 4 ch and a 1 ch. JL 300/4 ,alpine 35x4, and a jl 500/1. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
This is a somewhat strange question. I have a 4 channel and a mono as well, I think this would be the norm. Obviously there are going to be some INSANE setups on here (multiple mono amps linked together etc).
