Sorry it took so long to get back to you. Haven't had much time to play on here. The shop that did the install didn't interfere with the airbag at all. It is higher in the pillar. Shouldn't be a problem.
Thank you. Quite proud of them myself. Cost a pretty penny for them and the sub enclosure but well worth it in the end I think. Can't wait until the new head unit and processor go in in a couple months. Then it will be audio bliss!!
