I did this by accident once. I had installed a car stereo, the older type
where the speakers had a common ground. Somehow the ground came loose and
the L/R speakers were essentially in series. I didn't fix it for a few weeks
until the novelty of listening to a stereo station and being able to tune
out parts of the vocals by playing with the balance control wore off.

| What does "AFAIK" stand for?
| I realize I can make a Karaoke machine but, that's not my intention.

| computer sound card and I will be using headphones to listen.
