Ohm load and Rms?
For once i'm stumped on this subject. I have a 10" 4ohm dvc sub. I was planning on running it in series, which to my understanding makes it an 8ohm load? Now if I bridge my 1000w max amp, which is 4ohm stable. How many rms will my sub be seeing. 250? The rms bridged at 4ohms is 500x1channel.

Image in link is how I am planning to wire it.
Thanks for your help. Sorry if this is confusing, as I have so many numbers on my mind regarding this. Probably a simple answer, so that is why i'm asking guru's.

I know max means nothing nowadays. Its a 10" Audiobahn 1051T and the Amp is RE Audio XT-800.2v3 . I really liked the old u.s. amps so I thought I would give it a try.

Ok your amp bridged is rated for 500w @4ohms, but it only has 1 25amp fuse so you are really looking at around 300watts. That is fine for the sub you have. Here is the problem you need eather a SVC 4ohm or DVC 2ohm sub to run the amp a the rated 4ohm load. Your current sub can only be wired series at 8ohms or in parallel at 2ohms. So if possible you need to exchange your sub for a SVC 4ohm or DVC 2ohm.

I'll admit I've been out of the car audio game for some 10yrs BUT some things never change...
That sub is rated for 300rms so wiring the 4ohm DVCs in series gives an 8ohm load resulting in 200rms from the amp (it's rated at 400rms x 1 @4ohms). I fail to see the problem other than you wouldn't be maxing out the sub? And having an 8ohm load on the amp isn't going to fry anything. If you wired the DVCs in parallel resulting in a 2ohm load them yes that would get ugly for the amp because it could theoretically try to push 800rms....well until it fried or the fuse blew. Personally I'd rather have a Class D amp that was stable at 2ohms BUT using what you already have isn't going to hurt anything. If anyone can argue that with facts & logic I'm all ears...
Manufacturer's site below...not sure why the other sites can't get their facts straight. Notice anything about the model number vs the peak output? That's a pretty common practice...although the better brands use their max rms value in the model number.
