I am selling my DQSX. I have only had it since June and it has only been in the car since mid July. I am look to change head units that will have a built in processor or a add on that I can control through the head unit. I love this unit and hate to see it go but as my system gets more complicated I have no need for it. I am asking $400 for this unit I paid $499 for it. I will not refuse a reasonible offer. Here are a few pics.
