I have a 2013 Toyota Tacoma Double Cab
I'm putting 6.5" Component Speakers in front and am wanting to put Coaxial speakers in back.
I've researched it a bit and want to go with Alpine or JL Audio speakers but the 63/4" Coaxial will not fit in the rear of my truck .6" to high.

Anyways what are my options besides going with a smaller speaker and would going Coaxial be better than a component for the rear?

Would the 6.5" component fit in the rear with the correct speaker adapter?
