i didn't go to automotive genesis today after getting the quotation from howiechoo that it will cost me RM100 to remove my front components, amplifier at the trunk and refit my front and rear stock speakers. so i decided to diy the whole thing with nefrideum's help.
Took 5 Hours to do the following.
Remove door panels (2x) to change the speakers.
Remove A-pillar panels (2x) to remove the tweeters.
Panel below steering to pull the cross-over cables.
Glovebox to pull the cross-over cables.
Handbrake panel
Middle console
Whole headunit panel inclusive of aircond controls.
Remove extra wires and RCA etc and reconnect previous wiring.
All panels from front passenger side to the rear seats.
Remove rear C-pillar panels.
Remove headrests.
Remove brakelamp
Remove speaker panel layering.
Then after installing all, reverse procedure

Also removed my instrument meter to remove those EL-meters I had.
