snails pace, hi. well i am waiting on a 20 to mod. it's my first time maybe i can help but bear in mind i am trying yhis myselfe for the first time. 1, i have been told by Trey Cannon that there is a slight increase in driver output but no degeration in sound quality. i have a tube tv so i am going to have to do the bucking magnet deal. dont know about plasma. if you type in HornEd on search and go down to his pic.67jpg you can see the layout of the woofers, horns etc. he told me to just take out your horns and woofers mark your wires accordingly then take a "deadhead" rubber mallet and tap on the motor board until it comes out may come out easy may take some time. then just transfer your openings onto your new piece of mfd board that you can get at lowes or home depot for $20.00 or so. then you need a router to put the step in the openings fpr your speks to sit in. flat black paint a couple 2or3 coats sanding in between coats then with liquid nail put the motorboard back in screw in your speks. and thats it. hope that helps a little bit. sounds pretty easy on paper.
