I finally figured out that my Escort takes 5x7" speakers in the rear. Who
makes 5x7 speakers that is worth considering. Also how successfull are those
speaker brackets? factory size vs custom brackets. I will be running the
speakers in parallel with kenwood splits off 100w rms x 2.

Which coaxial speakers can I custom fit into 5x7" locations as I tend to
like round speakers more that other shapes.
