Has anyone played with this? I never got around to it, but now I have a test CD and a CD HU to test with and was playing it on a sub. I changed to a smaller sub amp from a 150x2rms; a 190rms x1 bazooka ELA1190, but was running it on a battery at ~12.6V idle. The box is tuned around 35hz ported, it is a 10" 400w audiobahn clone. What I get with the smaller amp is under about 35Hz when I turn it up I also get a 40Hz tone at louder volumes. It may have been clipping as it was warm and on 12V. At 40 and up it did not do this. It has a 20Hz subsonic that seems to work. Is the amp getting some kind of harmonic or the box? I will play a larger amp again, don't recall it sounding that way but did not check it as well. The box is a qlogic 1cf but mounted the sub inverted and it is near factory specs for minimum size, looks ok on winISD. It shows -3db at 32Hz. Put a little stuffing in there too.
