'04 Mars Red C230K Sport Coupe (not Coup-EH)
After you find gaiex's guide to removing your door covers (search for it under his name, that'll help 
), here is some extra advice.
Get some door clips from your dealer: they're about $2. You're very likely to break one of the clips taking the door cover out or putting it back in. I only broke one myself, so get two or three just to be safe.
Also, I haven't been able to find reliable information on the speaker sizes, speaker depths, or speaker adapters required for this car. As far as I could tell by measuring, you need about a 6-1/2" crossover in the front, a 5-1/4" component in the back, and 1/2" speaker adapter rings. You've got about 1-1/2" depth on both front and back from the metal edge of the door to some obstruction inside the door. I found some promising adapter rings at Circuit City in their car installation department, but I have to go back with my passenger door cover off to make sure. I'll PM you to let you know how that goes, and PM me if you figure anything else out.
If you have any more trouble, PM me.

The speakers in the coupe are 6.5" both front and rear. (I replaced mine). I put in infinity's all the way around, with components up front and a coax in back.
Everything fit fine, with no need for any extra speaker adapters. The ones the came with the speakers worked fine, and I've got just enough clearance between the woofer and the window when it's down.
Depending on what speakers you use though, you may need some adapters. I'd suggest making them yourself. (And wire adapters for the speakers don't exist as far as I know - you need to cut them)

I was thinking about getting the new yellow pioneer ones, they got a high rating, but im still debating on it because Im not sure if i want to throw in an AMP, but I went to best buy, and i believe they mentioned a 6 1/2 rear 5 1/4 front? but they never said anything about adapters?
