yeah the pics would be great.
so you are planning to cut metal (damn) why and wher abouts do you need to cut?
i asume you have bolted the mdf surround to the door correct?
what id like to do is something similar with so JL ZR speakers they need 59mm mounting depth do you think that can be done without cutting metal?
cheers mate i for one really appreciate the effort your going to by documenting this
