Impact sensors are located on the front end of a car...And on the sides with side airbags. They must sense a certain force (around like 15ish-25ishmph) impact in order to trigger. A vibration such as hard hitting subs will not achieve what the sensors are looking for.
Yea I know about the Airbag sensors //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I was curious though if there was one incident with a faulty airbag going off from a hard bass hit... guess not //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
