    • 360 has a connector that may prove more difficult to remove

    • Remove circuit board by removing 5 phillips screws.

    • Pull the circuit board back.

    • The connector is glued in place (Why????). I used a thin flat screwdriver blade to carefully scrape the glue off. But you may have to hit it with a heat gun if it doesn't loosen up.

    • Note, that this connector has three prongs. You will need to get a battery specifically made for Big Blue 360.

    • 4 tweeters are all wired together and soldered to the amplifier board. You will need to cut or desolder the wire if you need to remove them.

    • Remove 4 phillips screws holding the speaker in place.

    • Remove the speaker.

    • Note that the speaker mount has cutouts to provide screw clearance. So they go in only one way.

    • You can continue the tear down on your own from here. Rest of the screws are exposed and easily accessible.

    • When putting the grill back on, you will need to solder the wire that was disconnected during dissassembly back on.

The AC plug cover came off on my big blue party. Is it possible to reattach it?

I tried to do it from the outside without disassembling it but no luck.
