speaker install help

ive hit a snag in installing the rear speakers in my 2004 coupe. i cant seem to figure out how to get the rear deck off. Any tips? any help is MUCH appreciated.

also, the holes in the doors to mount the front speakers are shaped funny. is there some sort of adapter i need? was an adapter supposed to come w/ the speakers b/c im not sure if i got one w/ my eclipse speakers (co-ax 6.5" se8363). if i did, i dont have the anymore. can i jsut mount the speakers straight on to the car door? thanks a lot in advance.

might want to post this in civic forum if no one helps in you in awhile.

but as for the rear deck. the screws are under the speaker. get in your trunk and look up at your speaker youll see four screws take them out and the speaker should fall out. make sure you disconnect the speaker first.
