"Have you driven under a ford lately ?"

 

I can't help you on their size but I can tell you that the factory placement of the rear speakers simply "sucks". They could have put them in the pillar above the seat but no, instead, they put them right there where the seat can act as a muffler for the sound.

 

The speakers are 6 x 8.
