Hello all. New member long time lurker. Came across an easy way to "solve" this old problem. After 5 yrs of looking at my speaker grills sitting a 1/2" above the dash resting on my Polk db351 3-1/2" speakers dome tweeter I decided to work out a fix.
It was easy just get yourself some flexible "bracket material" like this
And 2 8/32x1/2" machine screws and lock nuts. And make a small bracket for the outside flanges so that you can mount the outside flange under the dash pad and the inner flange normally. This will tilt the speaker just enough so the grills can be attached properly. So everything looks stock with no cutting or sacrificing. Hard to word but this is the end result. I hope the pics can explain better than myself. Good luck!
