That depends slightly on wether or not your Civic is a 2 door or a 4 door. On 4 door Civics the rear speakers are 6.5" round speakers. If you have a coupe the rear speakers are 6x9. The front speakers, whether sedan or coupe are 6" round. The front speakers require a pretty thin setup. I believe there is only about 2 inches of clearance depth for the speakers, so you should choose accordingly.
