I just finished replacing the front & rear door speakers & Sub/amp and everything. Everything works perfect. But the next day I noticed the Air bag light in the dash blinks and stays on while driving. I dont think messing with the radio caused this. What does this mean & what do I do? Is it a fuse, maintanance light to take it to the dealer, or bad air bag? Hopefully its a easy fix. Please someone respond asap. Thanks!
