Here are photos and instructions that I did on how to access and remove the front and rear door speakers for the '04+ Supercab. Click on each picture for more detailed instructions on each step.

Hope this helps anyone looking to swap out speakers

Nice pics, very detailed. If I hadent gotten a Haynes manual for Christmas this would have been very useful.

 

I also got some speakers, not the best but they sound much better than stock, install time was about 15 minutes a door. These are a direct fit replacement.

 

Same ones I put in my truck. They sound very good IMO.

If you order from crutchfield.com they always give you detailed instructions, along with wiring harness that plug into your factory speakers wires. Makes things very quick and easy.

 

Perfect timing! I just got my speakers and was about to attempt this. Is there any trick to prying off the two panels on the sides of the window? Thanks for the instructions.

 

Nope, just give them a nice pull.
