So you say we don't recommend taking this apart not that if you do the plasic screw connectors will break because of this defective design to start with. I have taken apart and fixed hundreds of electronics an I took this apart to swap out a bad CD player with a new one. but every plastic anchor broke due to a terrible design. Bose should put a note on all these units they sell saying if you open this up your up the creek without a paddle because of this flawed design.
