OK, I’m new at this, but this is driving me crazy. What speakers will fit the ’05 Armada? I see posts that note 6x9’s in the front and 6.5’s in the back. When I go to Crutchfield it doesn’t list a single 6.5 inch speaker that will fit the back doors in my beast. Basically, can I put ANY 6x9 in the front and any 6.5 inch speaker in the back, or do I need to abide by what Crutchfield says?

Is there a better site than Crutchfield to find what components fit the Armada?

FYI:
2005 Smoke Armada
Basic "non-Bose" Stereo System

6.5 rear.
Front has a 6x9 opening, but I wouldn't use a 6x9. Oval speakers don't sound very good next to high quality round ones. Many people put 6.5" or 7" component speakers there instead.
Here's a link to a titan. Door speaker openings are the same. ;)
