How do you remove them? the rear deck shouldn't be too bad It seems like the things on the bottom just pop up. I'm installing some pioneer ts-a1670r speakers and have all the wiring stuff. I'd just rather not go to best buy or something and be charged 100 bucks for something I could do at home. Thanks!

Also, if anyone has a link to a website showing detailed info for my car speaker system, that'd be a great help too.
