Just as the title says I am trying to find out if 8in midbasses can fit in the doors of an 04 TSX w/navi. They aren't normal the magnet of the speakers is actually in the front. They are Illusion audion nd8's. Any help you can give me will be appreciated?

 

Not without cutting and lifting and maybe custimizing the door panel.

 

It looks like the ND8s are a shallow speaker. You'll still have to do some major surgery on the door panel to accomodate the 8" width but it seems that depth-wise they would fit.

Not without extensive modification. The depth isn't an issue really, it's the diameter. The door panel can only really accommodate a ~160mm diameter speaker without trimming the panel. At 200mm you would not be able to center the speaker under the door panel grill - actually you wouldn't be able to get the door panel on if you tried to center it. I think it would be a serious pain in the ass.
