When you say need, do you mean its mandatory for him to put multiple pics and taking the back cover off(which I mind you usually voids warranty) just to sell it? No Offense or anything, but rarely you see gut pictures when selling, unless there is a defect, and/or customer requests it. And I've sold two amps for a total of $1800, one on here and one of CA.com, and I've never showed the inside. One amp I didn't even take out the box because it was new. Just opened the box and took pictures that way with user name and date. Anyways, OP, GLWS. I have a brand new aq2200d sitting right in front of me and there isnt anything that says removing this panel will void the warranty.
