I've looked on the forums via search and couldn't find this specific info. What are the specs on the stock Nak sub for a 2000 GS? I think I may need a small amp to power it, and that is why I need the specs of the sub. My current setup does use it, but the sound from the sub is very quiet. I wanted to have more control of the sub via a separate amp. Feel free to also suggest a specific amp to use. I don't want to get a new amp to control all speakers (including sub) if at all possible as I am satisfied with the power of the stock amp for the main speakers.

Thanks for any info.

You may wind up overpowering it, it can't take much power before distorting, has pretty poor dynamic characteristics, though I don't know offhand what its spec'd rating is. Best thing that many have done is to add an amp like JL 250/1 or PPI (using a line-level-converter off the existing sub leads) and replace the sub with a suitable free-air sub.
