4 Resonant Engineering 8's

So I've had my four RE 8's for 6-7 months now and I have never gotten all four of them to run at the same time and sound good. I have them hooked up to a JBL bp600.1 monoblock amp. I have the 4 subs which are 4 ohm DVC wired down to 2 ohms.
When I hook each one of them in, 1 at a time, each one works and sounds great. When I have 2 hooked in it sounds more middy. This might be because I didn't re-wire them to test 2 subs, I left the wiring them same as if I were gonna run all 4.
My wiring is all correct. When I have all four hooked in it sounds terrible. Any ideas?
Some pictures just for a visual. I only had two hooked up to the amp.

sounds like you have a sub or 2 out of phase.

Thanks for the fast response. What happens when subs are out of phase and how do you correct this? Thanks again.

you have a sub with the - and + wired differntly than the other subs. all it does is make one sub work against the other and causes cancelation. just retrace your wires.

90% positive unless your amp dosnt like the load or something is going wrong with it.

It's possible that I might have missed something, but I just got done re-checking everything and putting the subs back in the ride.
If their was a phase cancelation, why would each sub work when I plugged them in seperately? Is it some type of thing that happens when a few are plugged in?

if they are all in the same box with no divider then if only one is hooked up they will still move the other speakers like a passive radiator.

Yes I know that , I just meant that each sub sounds good ALONE. I got two of them to sound good still wired as if I was going for two ohms with all 4 subs.
Two questions guys.
Can running two for right now do damage to the other subs?
And how much juice is each sub getting right now (the two that are hooked up)?

I think together I'm giving the amp 4 ohms with the two hooked up. But how many watts are the subs getting?
