Get Alpine Type-R componants in the front and Alpine Type-S in the back. I stress componants for the front because it sounds a helluvalot better with the highs coming from up top rather than down below. (that is if accords have door speakers and not dash speakers.)

This is what I was going to do before I decided to get Type-Rs coaxials in the back as well.

These are 2 way speakers.

Why don't you check out Pioneer Premiers? I was looking at those before I decided on Alpine Type-Rs. To me they sounded pretty bright. I personally felt the Type-Rs sounded more full so I went with them, but, your tastes could be different. Pioneer Premiers are cheaper also. They're also 3 way (note that for 2 ways and 3 ways that are equal price, the 2 ways will be higher quality since 2 ways are harder to make)

Well, there goes my 69 post count...
