hey i just bought a 04 blazer xtreme. i need help, i cant figure out how to install 6x9 in the back i cant fig out how to get the panels off without breaking anything,

 

unscrew the coat hook and "oh ****!" handle, unbolt the seatbelt from the top, then just kinda pop out the clips. the top panel fits into the bottom one so pop out the top of the top panel first. you prolly cant get the bottom seat belt bolt out, so youll just hafta kinda hold the panel outta the way when you work
