I did it on mine,,was a PITA to do,but it works for now.
The stock sound bar is made of thin plastic on the underside,i lined the speakers up where i wanted and had to cut a bigger hole even though the magnets fit in,the speaker frame didn't.
The PITA was trying to get marks where i wanted the new screw holes,and while drilling the screw holes be carefull to ONLY punch through and stop as soon as you do,don't do like i did and wrapped the speaker wires inside on the drill bit and rip em apart..lol..and THAT was a PITA to try and get in there and fix.
Also,even though the speakers are fitted in nicely,the speakers don't get to use their full potential,the sound bar is very slim inside,meaning no room,so the speakers don't sound good cranked real far because they can't breath.
I'm soon making my own sound bar and put 6x9's in it
