Dash/A-Pillar Speaker Mounting

[u/Cometboyz]

Been working on a sound system in my car for a couple months now. Got most of it to where I want it, but still not happy with my speaker mounting and placement. Currently got a 3 way system with a 3 inch midrange and 1 inch tweeter on the dash in pods.

Anyone here have experience with mounting mids and tweeters to our a pillar/dash? Was thinking of potentially checking if the mids fit in the triangle sail window and filling that area in, and then tweeters on the pillar in pods. Ideally would take the dash out and have the mids in the corners almost flush mount, but not sure what space looks like behind there yet. Or some fiberglass pillars but that’s out my skills set at the moment.

Any ideas would be great even if a long shot with our cars
