Well nobody answered this so I will. The Size is very tight fit could be angle of box. I moved my subwoofer (box design by elemental designs) from right to left side. I unbolted and moved the OEM amp and mounted it like the BSW install guide. I moved the bluetooth to the top of the sub box. Panel still closes. Dont have cd changer or nav.. Will be buying the retrofit kit later on. I will then probably reroute wiring was thinking 1. relocate nav to under drivers seat. 2 relocate cd changer to glove compartment.
drawbacks of doing this mod..
1. Missing 1 bolt.. last nut on oem amp was stripped by bmw. I had to dremel it off.
2. Instead of ordering 1 right rear cover will now need left cover also..if i ever to go back to factory
PICS to come- still need to order box and sub.
