No BS and straight to the point, I like it. Aftermarket ones will have to be drilled and screwed in, I may make preparations for this now that the dash is out. Drilling the holes would be quite difficult with the windscreen in. I can not re use these speakers I accidentally destroyed one by putting my finger through it when not paying attention lifting the dash.
Smashing the windscreen is not required - it was removed in preparation for the upcoming paint job.
