So what are IA 40.1s and DD Z1a's going for these days?

well you can't get 40.1s new right now. not making them.

That is a shame because this was by far more dependable than my DD Z1a! I ran it for a year on a 16V system (18.3V-15.6V) @ .75 ohm daily and never once ever shut off, never got overly hot in a sealed trunk, just a great amp. Polo.

 
i paid $700 shipped for my 40.1 but I think I got a //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif deal that's why I jumped on it. The thing is mint..
