Dash speakers in '80Q (Grilles?)

[David Miller]

I just installed a set of 4'' speakers (middle of the road memphis ones...
forget the exact number... moveable tweeter in any case) in my '90 80Qs
dash.  While I did that I noticed the OE grilles that cover the speaker
holes are pretty much solid pieces of plastic.  I tried poking little holes
in one of them with a needle, but I don't have 10 hours free to do this
fully to both grilles.  The Memphis grilles are too large to fit, and I
prefer the original look anyhow.  Any suggestions of any easier way to do
free up those grilles?

Thanks,
David Miller
