Unbalanced to Balanced
I'm looking for an inexpensive way to convert an unbalanced (consumer audio) signal to a balanced one for input into my car's head unit (there is no aux. in, I'm hijacking the CD changer cable). I've seen several commercial units, but they were all very expensive. If a simple circuit diagram is floating around that would do the job, well then that's what I'm interested in.

Hi Matt and welcome. :)

I'm sure you'll find something

Balanced ouput
A simple and inexpensive way if that is what you want :

Single chip (< US$ 4), 4 x 9V batteries (to give +/- 18V), nothing else.

Alternative -- use a single-transistor phase splitter with coupling caps.

Have tried both. Works fine.

Is there some standard that my equipment will (probably) adhere to that you guys know of, or is a bit of testing needed? It's a standard saab head unit ('98 900SE) connecting to a clarion 625 6 disc changer.
