I forgot to mention that I would like either a dual 4 ohm or single 2 ohm. That is 8 ohm (at least the version listed on their website is) so that wouldn't get the job done. I'm only running a single 10, so I'd like to get the impediance down so that I can get cheaper power. Secondly that doesn't look any beefier than my Assassin. There isn't anything wrong with my Assassin, I'm just trying to find something better, which may not be possible. Can I have a sub rebuilt in the same basket for a reasonable amount of money? Is that even an option? If so could they change the impediance?
