Good question you got there.
Well as you can see, the speaker is too big that it will definitely overlap the metal supporter right?

(Overlapping adi)
I don't believe the assemblyman cause he talk crap want remove the metal and say later the wood might fall off cz no more supporter so ask me buy another wood?
It is just a gimmick so that we have to buy another wood from them that costs RM50? WTF.

Actually we can remove the metal supporter with pliers.
But first you have to open up the cloth that covers the wood.
After that use the screwdriver to cungkil the dead bolt to remove the whole thing.
After removing the metal supporter, start drilling and makes holes for your speaker.
As you can see there is a line stain that shows the previous location of my metal supporter.

Once you done with the hole and making sure the speaker is in place, take out the speaker and put back the metal supporter with screw and nut.
Get from DIY shop la.

Tada. I refit the thing.
Remember you have to drill another hole to fit it.
Overall DIY yourself is better
