You know he did the right thing about coming on here and asking, cause sometimes dealers donT know everything, they sell. I have been to car stereo shops and have asked the sales person about a product in which sometimes they know very little or much at all. I bet some or many of you have dealt with similar sistuations, in which you knew more about the product then the sales person. I respect this person for asking questions, instead of just assuming and having a pissed off customer that will bad mouth the shop or store.
