if it were me, i wouldn't be relying on battery power to run that at .5 ohm, i would put money into a couple of really high quality, high output at low rpm alts.
wouldn't let it trouble you too much. being blood doesn't mean anything really. if someone isn't in your life at all, what does it matter how they are related to you?
It's around a 2.5 to 1 and it peaked at 48hz. But it is real musical, thats what I was after!
We all know that some ratios and a peak tuning are not enough enclosure details for Triticum...lol
I would wait and see what other people say, the 3000 might be fine too, I'm not really familiar with that sub. But me personally, I always tend to shy away from almost 2x RMS on a sub for daily use.
If you are worried about how much electrical you have you could just run a smaller amp. That is a lot of power, you probably wouldn't be disappointed running the SCV-2000d. Just my opinion though.
The problem with using them is they boost around a certain frequency. if you are literally only playing that one frequency they are fine, otherwise they usually aren't helpful. i personally would leave both turned off
