Click the link in my signature to see if it's something you want to tackle yourself.

I will note that my system is 9 years old and it has changed some since then, but the basic idea/install is the same.

I too have two systems, an 8 year old install in my C10 and 3 year old install in my 65 Mustang. Very pleased with both.
