Is there a way to hack the firmware so I can adjust the volume on my pb turned in to a keg. I use the kenwood fm modulator and the difference between my stock cd player and the keg is huge.
no there is not. volume control is fixed in the firmware for each type of head unit so as not to over drive the input capability of each head unit. it could also be that the output of the fm modulator is less than desireable.
Ya I think you're right but I just read that there is some adjustments I can do on the modulator.
