I have a 2007 350z hr that is very low to the ground, when I was driving the bottom of the car hit a bump in the pavement very hard and the sound system, dash lights, and power mirrors instantly went out, I’ve changed fuses and went under to car to try to find anything and so far nothing, any suggestions help

 

Bottoming out a FM chassis can be hard on a lot electrical components. Check the chassis grounds, battery cables and IPDM connections.
