I'm back with my dual 3.5" speaker brackets

Also, an advantage of the two 2.5's is you get stereo imaging with your sound. Incidentally, i have been working on a prototype for a mount that will allow the early a-body owners to do the same thing in the 6x9 hole in the dash. Further, if you car has a package shelf, I am working on one that will allow you to mount a small 8" sub in the center hole. If there is any interest, i will expedite my work, and get them on here.
