I would like to put my MTX Thunder6000 T6.6 Components in my 2005 Accord. Will they fit? I figure with a little modification I can massage them in there, but would like a secon opinion. Here is the lowdown on them.

Top Mount Depth - 2 3/4"
Cutout Diameter - 5 3/4"

 

I don't see why not, you have to trim a little to fit even a 6.5. So for a 6.6 I don't see a problem. The stock speaker is a 6.5, but the cutout is oblong and not big enough for an aftermarket 6.5.

EDIT: Your also going to need a 3/4" or even 1" baffle or the window will hit the speaker.
