Just went and pulled one of the stock speakers to see what kind of room I have. Not much at all. Mounting depth is very limited. Stock looks about 1.5" or so.. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
I shoulda took a picture of the 20 year old paper stockers. The one I pulled out litterly fell apart in my hands. :0
