JL 500/5 or Memphis 16-MC600D ?

Yes the specs are different, but I was essentially only looking for opinions on the SQ/reliability difference since either amp would work for me. I was leaning towards the JL until today, so it looks like I have a little more research to do. I have heard nothing but good things about Memphis so more than likely thats what I will end up getting, but I'm still willing to look at other brands if anyone knows of something of the same quality or better.

On another note, one thing about the specs that did make a difference to me was the 100x2/25x2 on the JL vs. the 50x4 on the memphis. I understand that doubling the wattage to a speaker doesn't even come close to doubling the sound level, however I dont really think I need the 50wpc to the rear speakers as they are just intended for filler, and I would like to have the 100w up front if for nothing else to make me feel better. (125w rms speakers up front)

I have a 2dr yukon and the rear speakers are a pretty far distance back, so maybe I do need a little more power back there? Any opinions or knowledge on that aspect?

Thanks for the replys, I know that a lot of this stuff tends to be opinion based but I haven't had any experience with either JL or Memphis amps, so I'm trying to see what the general consensus is.
