100 series speaker nightmare

Hi guys and gals , just went through a speaker up grade in the 100. What started as a 1hr job , turned into a midnight run. The problems i had were.... The genuine speakers come in the own case that bolt to the door , if you purchase the same size , they sit to far in and hit the window. OK you say, just get a spacer , WELL, not so easy. The spacer isn't wide enough to meet the inner door panel to screw it on. SO .. the verdict. Take the original speakers , cut away the inner plastic , remove the outer cone with a screw driver . slightly grind the lip so the new speaker sits in . solder 2 wires to the speaker and pass them through the wire cut outs and attach the new assembly to the door . looks like the standard set up and works great. I know it might be a bit of a boring read for some , just hoping to save some Panadeine fort to some who may wish to do the upgrade .

Big thank you to No Limit for the tips allong the way .
