I did a search but did not find an answer to my question. I bought an 08 Expy EB with the 6 disc changer, 7 speaker set up. Am I correct in that you cannot control the level of the subwoofer? I came out of an 08 Honda Element SC with a slammin little factoy stereo set up that allowed control over bass and treble as well as how much sub you wanted to dial in...I am not seeing that option on this Ford. Being a pro audio guy, this bums me out to no end.
