JL Audio speaker fitment??

I have a 2008 Tacoma Double Cab. I want to upgrade my speakers to JL Audio without adding an amp or running new speaker wires. First i wanted to know if 6x9 can fitting in the rear doors? ********* has 6x9 and 6.5 kits. The JL Audio site and other sites have different sizes for the same speakers. TR600-CXi is a 6 in. speaker and TR650-CXi is a 6.5 in. one. Yet crutchfield and other sites explain that the 650 fits most american cars and 600 fits japanese. something about "true fit"?

Anyone have experience in this? I dont want to purchase speakers that wont fit correctly. Thanks.

 

First off, get your thread moved the audio forum (ask a moderator or start a new one in the right spot).

Secondly, do some research in the Audio forum: http://www.tacomaworld.com/forum/audio-video/

Finally, contact Mr. Marv for your baffles. ********* has a bad reputation for service and Marv has a great reputation for service. He'll talk you through it on the phone and set you up with the correct gear.
