providing you mean the grill and i think u got a gen 4, they stuck to the parcel shelf, and from memory its just melted together. but by the sounds of it u just wanna change the speakers so you. 1. pull back seat base out, just pull up from the front at about 30cms in from side. 2. take out seat back. ummm gotta remember 3. take side rear A? frame covers (the covers from parcel shelf to roof cant think of right name) 4.unscrew child seat bolts from parcel shelf. 5. remove 3rd brake light assembly. 6. yank :P nah theres i think 3 clips holding it down, work out where they are and release them by pulling at certain points,should come off. 7. remove stock toyota speakers NOW you have 2 options. 1. make mdf brackets or 2. drill new holes, because the toyota speakers have a 3 bolt .....system :S and normal speakers have 4 once u mount the speaker n wire it up, just reverse order to reassemble. i think you can skip step 1 + 2 but it just makes it easier and sorry if ive forgotten anything....havent done it in a while
