Since this question is asked almost every day, I figured it would be a good sticky to have around. I compiled all of the speaker sizes for civics. However, this does not take into account mounting depth. Hondas are known for shallow mounting depth inside the doors, so spacers may need to be used to ensure proper fitting.Also, fitting 5.25 speakers in 6.5 mouting holes will often require smaller adapter brackets.
