I'm doing a Nakamichi MB-75 6 cd changer in the dash am/fm with amber display. Use Nak speakers and a 8 inch sub. Did a system like that in my 95 540 sport and sound real sweet. Good luck -Rick This week I'm going to upgrade the stock deck in my 6er, and it seems that pioneer is what every one is recomending, just thought I would ask you guys what you think is the best deck for the 6er?
