What is the 2007 ford f150 speaker size?

The factory speakers in Your 2007 Ford F-150 are 6x8 in the front and rear doors. The 6x8 size is very uncommon and Ford is one of the few auto manufacturers that use it. Because of this, You won't be able to easily find a direct replacement from an aftermarket manufacturer that has a decent price to performance ratio. The easieSTSolution is to replace the factory speakers with 5-¼ components in the front and rear. To do this You will need to use an adapter that lets You mount them in the oversized 6x8 opening in the doors. Other than that the only thing You need to be careful of is making sure the new speakers are not too deep which would interfere with the window track and stop the window from going down all the way.
