I'm not sure what ASL you may be referring to though. It has SSP, which is Scion Sound Processing (equalizer modes).

oops...
No, I do not think it does. From the manual and setup, I've never seen that. Usually there would be an option to turn this on/off or set a level 1, 2, 3...
I also don't see a place for a speed sensor wire (would have to be available on the harness).

Well, I stand corrected. It's in the manual and it does have ASL (Automatic Sound Levelizer). I honestly never played with it (I totally would have if I read the manual). It has adjustments for Off->low->mid->high. It says it monitors varying noise and automatically increases the volume level. By that statement, I would assume that it's doing it without using a speed sensor signal.
