hiding screw holes, mounting trunk lid fg

Heres the thing iv got the fab. part of  fg down iv made a couple boxes . Now i want to do my trunk lid iv see alot of realy nice and clean installs  and you can never see how it was mounted.(im sure thats the point).  i have a mdf skeleton for 16-5in mids on a smoth 90 angle i havent wraped it yet  i need to know the best way to get the cleanest look when mounting it  ie.. i dont want to finish it and just drill holes thru it to the trunk lid.          this is the only pic i have of the trunk lid.          any input would be extremly helpful    thank you.

Take a look at this thread. It'll give you a good start if you are looking to not make any holes. Just adapt modify and refine it for your needs
