Renault Megane is technically a family car, but it is a small family car. It can be purchased as a 3-door or 5-door hatchback. However, the 3-door is not technically a family car because of the limited space it offers. If one has a bigger family, a bigger car is recommended, such as a mini-van or SUV.
The standard size for Rear speakers and Door speakers is 6X8 or better known as 5X7
To remove the door panel of a Renault Megane, start by gently prying off any trim pieces or covers to access screws and fasteners. Typically, you will need to remove screws located near the door handle, armrest, and at the bottom of the panel. Once all screws are removed, use a trim tool to carefully detach the panel from the door by releasing the clips around the edges. Finally, disconnect any electrical connectors for window controls or speakers before fully lifting the panel off.
To remove the door trim on a Renault Megane, start by gently prying off the plastic cover near the door handle using a flat tool. Next, unscrew any visible screws securing the trim, typically located around the edges and behind the door handle. Once the screws are removed, carefully pull the trim away from the door, starting at the bottom and working your way up to avoid breaking any clips. Finally, disconnect any electrical connectors for window controls or speakers before fully removing the trim.
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.

The Honda Accord Coupe built in 1999 has 6.5 inch speakers in the front doors. These speakers have a depth of 2.9 inches depending on the exact interior package purchased.
