You'll be dealing with cracks in the sheet metal, particularly where there are corners. Need to weld those up periodically. Can end up with holes in the floorboard, but again, weld those up periodically. Biggest issue is the door strikers / latches. Once those crack, you need to weld a thicker piece of steel there and it shouldn't give you issues again.
Don't really have to worry about windows breaking until you're into the 160s.
About the only vibrational mechanical issues I've seen from stereo stuff are sometimes the brake lines coming off the master cylinder will fatigue if there's too much firewall flex. Aside from that, most of the issues are from weight. You'll quite literally double the rolling mass of a vehicle with all the equipment you put in it. Go through brakes and wheel bearings like candy.
tl;dr, issues are primarily cosmetic sheet steel. Structural items like the frame are OK.
^^^ my armchair guess is that SnowDrifter has some experience or been close to it here. to me this post wins. and also shows that the vats majority of car audio won't come near to this.
BIG acoustic pressures will act against surface area, and all of his observations align with that.
It would be interesting to see if insane mid-freq (say 1 khz) would start to fatigue vehicle circuitry.
