Ohms question

[RebelDogg 10+ year member]

Search doesn't seem to be working, so sorry if this is a question that's already been talked about.

Here's the hypothetical: a sub with 1000W RMS, 2 ohms DVC wired in parallel for 1 ohm

You have two of these subs in one box and you need ONE amp to power BOTH.

What I can't decide is if each sub is set for 1 ohm, does the amp encounter 1 ohm impedance or is it 0.5/2ohms?

I'm not sure how the wires run (or if that makes a difference). If there are two speakers, are there 4 wires running in the box to them? (2 pos, 2 neg) or is there a positive running to one speaker and a negative to the other, then the 4 voice coils wired together in parallel?

Real world prob: TS-W3001D2 (Pioneer 12" 2 ohm DVC, 1000W RMS, trying to find an amp to power two of them. Want to do an all Pioneer system if possible, but that's not really necessary.)

P. S.

I don't have the speakers yet, I'm just looking around. There is a 4 ohm DVC version as well. Also, I really just want the answer to the hypothetical, but I'm open for suggestions to the real world problem as well.

Lastly, just as a quick side question: would this sub setup (2000W RMS, 6000W Peak) along with 600W (peak) of door speakers require any extra batteries, new alternator, etc...?

That should help with the majority of your question.

Thanks! Fixing to read it now.

Edit for above:

Looking at Hifonics BXi2008D 2000watt amp. Any opinions? Never heard of Hifonics (never heard of a lot of things, I'm new to all this!)

Edit:

SeanDub: THANK YOU AGAIN!!! I wish I'd have had this a few days ago. I've been running this crap through my head trying to figure it out and in thirty seconds it all came clear. I think I kind of knew it all along, I just needed it verified. Now to move onto my next headache in teaching myself car audio!
