I believe they were single 4 ohm only, but there was another model (I think it was 10.1d?) that might have been DVC with more options. PSI looks like a great company, but outside the price range of this sort of goal. I didn't know there was a single run production house for one off subs.

I found a post discussing the differences between SGI and SGII
. If I take 276 divided by 6 speakers I get 46 watts per channel. If I take 368 divided by 8 I get 46 watts per channel again. I'm guessing all channels of the BA amp get 46 watts per channel. I'm also going to go out on a limb and guess those are peak ratings? Maybe RMS, but if the flea market brands advertise peak, I'm guessing car manufacturers do too. Going out on another limb I'm going to assume we can just divide by root 2 to get RMS from that (that's a bit of a leap), so about 32 watts RMS for the sub. There's some assumptions in there, but I think they were reasonable. I'm more comfortable saying 32-46 watts RMS per channel.
