Greetings all, I'm new to this thread and also a new owner of my Tundra. Love the truck. I'm going to replace the head unit this weekend with a Pioneer FH-P8000BT. I've also ordered some Alpine speakers SPS-619 6X9 for the front and SPS-610 6.5 for the rear. I've done some research on this forum and have found a lot of great info on how to build my own speaker adapters and so forth. What I have not seen discussed are mods to the door panels if needed to accomodate speakers that don't fit (according to Crutchfield). Has anyone had to do any mods to their door panels to make sure the panels fit securely like they should without interferring with the newly installed speakers? I'm looking for dos and don'ts. Any info or tips are greatly appreciated.

If you build your adapters correctly, there will be no modification to the door assembly. I'm running the same setup 6x9 front, 6.5 rears, and both fit with no metal cutting or bending.

check How do I install stereo, speakers, subwoofer, amplifier, tweeters ipod in my Tacoma Toyota (http://www.tacotunes.com) they may have the info your looking for but, I put the 6X9's in front w/o mod to the panel, only had to build the spacers. two banana

Thank you guys! Starting on it today!

You can get nice adapters on Ebay for about 20-30 a set which makes things much easier.

If you make adapters out of wood, I'd suggest painting all sides of them. Moisture builds up down behind the doors, and could potentially rot the wood.
