just now, while driving home, my rear board start producing very annoying sound...

sound like.. when u open n close door.. that 'eekkkk' sound..

very annoying.. i check n that sound came from my rear board..

i think its because of my 6*9 speaker on it.. n the board cant support it..

when my car go bumpy.. the sound is there..

so do i need to change the board / modify it ???

how much ??

direct take away lo...

change to a mdf board lo... sound proof it also... haha...

U driving aeroback car? If yes just screw permanently the side of board.
