Thanks to everyone in advance. I love this forum. I am buying a 2013 Base MDX on Tuesday. I have read everything on this site and others. I have a few technical questions I can't seem to find answers to. Looks long, but most are yes/no.

1)What is the max preout voltage going from the OEM into the factory amplifier?
2)Does the output voltage vary with the radio's volume control?
4)Are all the headunit's outputs full-range?
3)If so, has anyone measured the frequency response of the OEM head on each output?
4)Has anyone measured the frequency response on the output of the amplifier?
5)Are all amp outputs fullrange?
6)If so has anyone measure the frequency response?
7)If they are not fullrange does anyone know the frequency range of each output?
8)What is the impedance of each of the 8 factory speakers?
9)Are there any passive crossovers in play?
10)Is the base model amplifier still under the passenger's dash?
Thanks
