Power wire ?

Right now I am running 1/0 from tha battery to the D-Block then 4G to my amps.But I am changing my system, and I have 2 xtant X1001's and 2 xtant x604'sDo they make something bigger than 1/0 or can I just run 1/0 to all the amps

According to Xtant, each of your amps requires a 120A fuse.  Really what that means is that when they're being pushed to their max they'll draw maybe 110-115A.  But still anything more than 350A total is probably too much for a single 1/0 cable.  If you don't push the amps very hard then they won't use anywhere near as much power and you could probably get by with the single 1/0 wire.

I know that they say that the amps will accept up to 1/0 gauge but that doesn't mean they NEED 1/0 gauge.  If they had a fuse rating of 250A each, then I'd say that yes they do each need their own 1/0 gauge connection.  But when you check out the "fusing requirement" for each amp, it's only 120A, which can easily be handled by a 2 gauge wire.

I've never seen anything for car audio that's bigger than 1/0 gauge, because once you get up to that amount of power you're almost always looking at a multiple alternator/multiple distro. block setup.

 Just out of curiosity, what kind of alternators do you have (or plan to have) running, and what are they rated for?

well at this moment I am looking for an alternator

I have a 2002 ram Quad cab, Have not yet found out what the factory one puts out.

But yes I do need another one

Any suggestions will be gladly accepted

Thanks
