I am running a Pioneer 6000UB with all Memphis MClass speakers, 6x9 MClass rears, and MClass 6.5's in the front. Mine are the old school Memphis that still had the swivel tweeter head on them
I actually found my Infinity 4" speakers in my 6x9 box when I was looking for wire caps. I was half tempted to install them
Also I wish I had known a bit more about Pioneer's Premiere line of HU's. I actually thought those were a lessor product back in the day until recently I discovered the exact opposite of that.
I think I will throw my setup on their site to see what they say. Should be interesting
