Sorry...

Update:

I just rewired my Sony CDX-F7700 to use its 4 volt pre-amp outputs. While it did indeed sound clear and sharp it was a lot quieter. To make it semi-loud I had to turn the volume up to about 50% to 60%. To go very loud it was almost full volume. In contrast when I switched back to the speaker wires out from the Sony, to make it semi-loud the volume needs to only go to 25%. It is very loud at 50%. After I switched back to use the speaker wires I did not notice any differnece in clarity or quality, it still sounds damn good and a lot louder.

You results may be different...
