Reubent, Thanks for the information. My ideal setup would be to run the speaker level line out to the sub. I know that the original T-amp would be ruined in this scenario. I believe it was because of the common ground and shorting out of the signal, thus frying the chip. Does this same precaution apply to the Icon? I have yet to hear back from Nuforce and there is no mention in the literature. Hopefully someone has tried this successfully.
