I have side airbags, if you check my sig you can see what I have installed. Also if you do a search there are pictures of my, alpmans, and soundguy's sub installs, all a little different but you get the drift. Also Alpman has a tutorial that will show you speakers installed in the door. It took me roughly 45 mins to completely take out the old stereo and install the new head unit. It took about 3 hours to do all the speakers. You will have no issues at all. They put that disclaimer in there to cover their asses. As long as you aren't an idiot you're install with go smoothly and quickly. Hope that helps
