Do I need a different enclosure with the Bluetooth kit? When I connect BT kit it doesn't fit in the metal enclosure that came with the JB4. The picture in #3 of the install instructions looks like a plastic enclosure, but #4 looks like the metal one that came with the JB4 kit. Sorry if I missed something but I tried searching and couldn't find the answer. I ordered the BT kit with the JB4 but it didn't have an extra enclosure with it. I'm trying install the JB4 right now and it doesn't fit in the metal enclosure when the BT kit is connected.
