The 2007 Ford Focus will use 6x8" speakers in the front doors and those same 6x8" speakers in the rear doors also. The cargo area will contain an 8" subwoofer. These two speaker sizes in the doors being the same means that it will be really easy to buy an upgraded system if You so desire. If You want to purchase a more powerful Audio system for Your Ford Focus the total cost will range between $400 to $1000+. It might not be worth it for all owners but for those that love their music You'll likely want to give the vehicle more of a boost than it has stock.
