Well i have a situation. I'm upgrading to 2 SA 10's for my setup from 1 12. I am needing D4's, but sundown is sold out of B-stock d4's (little imperfections don't bother me, so why not save $100 by going B-stock). I'm thinking about getting D2's, but that means i would have to wire to .5 ohm to the amp. However, the last few boxes i've made have given a 2x impedence rise, so therefore i will probably see about a 1 ohm load to the subs. My amp is a Powerbass ASA1500.1D. I have never wired it down to .5 ohms before, but it's a very stout amp and i don't think it would be a problem considering the rise would bring it above .5 ohm. But i would like some opinions.
Before anyone asks, i do have the required electrical to back up a .5 ohm load, so that's not a problem. I mainly listen at lower volumes, and only turn it up loud periodically or for competitions.
