yeag, well.... your amp WILL produce more heat, that's a fact you have to deal wit I'm afraid. Unless you buy an other amp for your sub. (monoblock, or a 2-channel.

just take care of the heat-reproduction. add 1 or 2 fans and you should be good. the heat won't be of that matter that you'd burn your fingers or something by touching it.... well.... at least it SHOULDN'T be.....

might want to reword this. the way you wrote it, it sounds like you said he was gonna blow his subwoofer feeding it 100 rms. not true!
dont get me wrong, I agree with you that likely he would not like the 8 ohm performance as much as 2 ohm performance due to output differences.
however, I recommend everyone check out this thread which discusses the advantages and drawbacks to running at 8 ohms versus lower imedances:

Well, I have deceided to sell the Soundstream D'Artagnan 5.1. I will be looking for a old school Rubicon or Referance Soundstream 5 Channel. I have listed the one I have on the For Sale Forum on this site and if anyone hears of a older high end 5 channel Soundstream in excellent condition becomes available let me know, Thanks AL.
WhiteRabbit is right! You will not run the risk of blowing your amp or sub by running a higher ohm load. You are simply resisting the amps ability to run current through the sub. By doing this, the amp would actually run cooler and have less distortion. But conversely, you will notice lower dB levels.
True! I'm not as conserned about dB levels as much as run temps and THD values. I'm not looking for the Doooom-Doooom thing just clean accurate sound, AL.
no, you'll not be at risk, running it at a higher impedance load. BUT, you WILL be at risk underpowering it in a pretty extremal way!!!
and, once again, it's all in the tweaking and tuning. if you don't set your gains right the sub WILL blow with feeding it only about 100Wrms. remember the sub is a 300Wrms one, so it's extremely underpowered.

Just an up-date on this.. It's been working for a year now
I ended up connecting a 'y' cable to the 2 'sub out's ' on my audiocontrol equiser then running a single (mono) cable to the amp where i went back into a 'y' cable and into both of the amps inputs.
I set the switches on the amp so the internal x-over was off and it was in stereo mode.
I then ran from the left output to one voice coil and from the right output to the other voice coil.
The sub was fitted in to a 1" thick mdf box that I made up to the dimensions on the sheet that came with the sub.
How does it sound?
Very good.
It's only a 10" sub but it works well. After trying all ways of wiring it up this way 'sounded' best.
I got it to go louder by wireing it up other ways but this way is a nice clean sound and it will still make the truck rattle in many places. I have a audiocontrol epicenter and if you turn it all the waay up the sub will bottom out on its coil but it holds together fine until about 75%.
I'm happy!

Well guys I went with a Zapco AG 650 and very happy with the SQ!! I bridged the 5&6 on the sub channel and the amp at 2 Ohm impedance has not broke a sweat, AL.
