Mazda Astina 323 SOund system question
 

hey all

Im just installing a full stereo sound system into a friends Mazda Astina 323 (03 model) and was just wondering how do i remove the panels around the original head unit (stock cd player)??

Also is it safe to cut the 6x9s into the parcel tray, because the parcel tray lifts up as the boot door opens, so would it be alright to cut them into that???
