Anyone know what size speakers we have in the truck? I have an extended cab. 1 in each door and two in the back.

 

6.5s in doors, 6x8s in back

 

If you're handy, you can make 6x9s fit in the back like I did

 

Do you have any pictures of the cutout? I'm curious how much modification you had to do.

Post pictures of the front of that plastic cover please. I just made the mistake of getting some verrrry expensive 6x9s

 

Why the front? Its just an L shaped piece of trim that the 6x8 screw onto, so because the 6x9's don't line up, there is a lip where the speakers sit on, so i drilled 1/8'' holes on 4 corners on the lip and used zip ties to hold the speakers, then I tightened the ties to center the speaker making it so 1/2'' sticks out top and bottom of the cover.

To get the speakers in, insert the top end in first, then use a screw driver to pull the trim over the bottom portion of the 1/2'' thats sticking out then screw the cover back in. No one would ever know that there are 6x9's in there.

 

I need to go outside and look at my extended cab. You wrote this as a response to an extended cab question, but I'm starting to think your regular cab housings are entirely different.

 

They both should be the same.

 

Minus the seat belt, I believe the back should be the same
