hey i have a problem, i needa put my two front 6.5" speakers in the front of my 93 magna TR and needa know what do i cut the skins with and is it hard to do it, i also needa cut the holes in the back for the 6x9"s and was wonderinf how hard this would be and what i would do goin about cutting them??? how do i do it?

I used a Jigsaw. Cuts through it like a hot knife through butter.

Need to remove any door map pockets in the front door trims, then simply use a jigsaw or dremel tool. 6x9s in the shelf is easy; just remove the standard 6" then the adapter plate. Mark the cutout area required on the carpet and just cut out to reveal mounting holes.
