Ive been thinking about a SG mount for a long time now. So I fabbed one up. If you worked straight through from start to finish it will probably take you an hour or so.
I could have just drilled 3 holes in the speaker cover but I dont have a spare cover.
Its also reversible this way. I do plan to cover the surrounding hole with coroplast or something.
This probably cost me $5 to make.
What I used:
Thin cardstock (for template)
Thin sheet metal
Metal snips
Metal file (to smooth edges)
Drill
Screwdriver
2 Screws
3M Velcro
I had it behind the steering wheel but its not a great place since the surface is curved.
(It'll come off eventually in time)
So I popped the speaker cover off.
My echo didnt come with tweeters so its an empty space with 2 places for screws.
I made a template out of cardstock, traced it to thin sheet metal,
then cut a plate using metal snips. I then smoothed the edges and
and screwed it down to the existing holes.
3M heavy duty "velcro" works really well and I was able to run the cord down.
(If you look through the windshield, it literally drops straight down to the OBD port)
I like how close it is to the windshield. I keep my eyes on the road
and even have a small amount of room to put up the sunshade.
