Simple speaker holders for making custom A Pillars.  Designed for the Blam Signature line, make sure you have the same tweeter or you might have to change the diameter of that mount.  The mid mount has two pieces to make it easier to get them perfectly level in your car.

Basic idea is to do the 3D print the speaker holders, aim them with super glue, build up around them with popsicle sticks and then go over the whole thing with body filler to make it strong and give the desired shape.

Only difference between V1 and V2 of the mid alignment mounts is that V2 has a bit more adjustment and slightly larger holes to make mounting easier.  I used V1 and had to slightly sand it.
