my friend and i got his m3 installed a while ago and he decided he wanted a bass knob so we went to install that and lo and behold, no slot for bass knob. help?
you have the first generation M3 if there is no jack ...It wasn't introduced till the 2nd generation modelWas this a build house mistake or something. I would send it back.
