sub choice factoring in ohms

[obsidianbasshed]

Alright here goes. Right now I have 2 obsifian d4 12s. I'm going to be adding a 3rd sub. Going to be powering them with a soundstream rub1.2500.

My question is should I just add another d4 sub and wire them to .67 ohm and hope for box rise to get me over the 1ohms that the amp is stable at so I can get the full potential of the amp

Or should I sell mine and get the 3 d2 obsidians a buddy of mine has and wire them to 1.34, knowing I'm going to have box rise and won't be getting all I can get out of the amp. Going this route I know I'm safe, it'll be easier on my electrical and I'll still be getting 1700ish watts Rms which is around 566 to each sub.

I'm only going to be running 1 yellow top in the back. stock battery I. the front and some 0 gauge cca for wire.
