question on sub

Ok i have two american pro 8" subs-its the 250 watt model, yeah i know they are crappy, but thats not whats this is about- im building a folded horn for them and i have heard that even the crappiest subs sound amazing.  Its for my step bro who how has my 79 civic beater....so i thought it'd be funny as hell to add to his ghetto setup.

I need the info on them- like Q and Vas

Is there a way i can test and figure out for it if i can find that info?  That info is becoming impossible to find btw.

A good article from Rod Elliot:  http://www.sound.westhost.com/tsp.htm

Building a folded horn cabinet is probably the most difficult challenge for any enclosure builder.  I have tried a couple of times and have never gotten very good results (but then again I am really not that good a carpenter!)  Go for it but measure and measure again and follow a really good set of plans!

Finally having some time to sit down and read it all....i need an Audio frequency oscillator according to them...couldnt a tone generator off the net work then burned to a cd? 

Also, the power amplifer- that'd just be the amp i'll use right?  but how do i get the power input down to .5-1 volt?

Looks like ill need to get a DMM, i have a el cheapo analog.  I've always wanted a nice DMM. now i have an excuse to get one.lol 

resistor can be picked up at radio shack couldnt it...
