Need real time analyzer software.

[Newnoise]

Hey! all of you audio gurus. Here I am once again. (Boy, i need to get a life) Well, Trying to tweek my system and am having trouble using this crummy audio analyzer program that i have on my laptop.Its frequency range is 85hz to 10914hz in 85hz increments. I am not looking for a super-high performance Iasca Real time type analyzer. Just looking for a program that I can put on my laptop and use a decent mike to tweek my EXp2 and kind of get an idea as to what my frequency response is so I can set a decent frequency curve according to my vehicles accoustics. Don't really want to pay 50 to 100 bucks to use a shops equipment.I am starting to scare myself. I think that I am getting much to serious about this whole car stereo thing. Oh well, I am having fun. Poof! There goes another paycheck!Thanks for any info that you all might have.
Sincerely,
Newnoise

Check out DOD on the web I remember seeing an rta for about $300 or so with the mike and internal pink noise generator.
