I know some of you out there have questions regarding electrical systems, wiring, LEDs, Ohms, Watts, Volts.... so on...
So here is a link to bookmark!

(links on the right)
Here is an overview:
This site will help you to understand basic electronics and some electronic devices. It will, of course, also touch on car audio acoustics and car audio equipment. To make the lessons as painless as possible, you'll find hundreds of diagrams and pictures, .wav files and more than 50 javascript calculators on the 125+ individual web pages. If you make even a modest effort, you'll learn more about car audio electronics than you ever thought possible.
This is THE BEST website i have seen out there with such a collection of information.
The best parts are the "java calculators" that let you input various items to calculate for a desired outcome. -a total life saver.
For all those interested in Car audio or just in all things electrical, this is a great tool to have while planning, or fixing your projects.
I have used this many times on my projects. Then after a computer crash i lost the link for some time... Lucky enough to find it again.
EDIT:
Another addition to the knowledge collection is:
http://www.the12volt.com/
If you look through the menu at the top, there are a lot of great links for various projects, along with calculators, and other usefull car info.
There is also a forum where you can post specific electric questions. I was provided with some usefull project diagrams and project help. The forum has car audio/electrical installers posting and answering questions. Though the MB is pretty limited in its options, perhaps you can find info for your other cars there as well.
Enjoy!
