i've noticed the potential for speaker damage but have managed to avoid it so far.
i have taken to doing a little class on "how to enter the car" prior to anyone else getting in. especially on the driver side since my brother got all jammed-in trying to sit in it. thought we were going to have to call the fire department to get him back out. i would like to say i was worried about his well-being but mostly i saw various car parts getting wiped out as he was getting in (never did make it all the way in) and out.
1)face away from car.
2) let butt fall into seat.
3)slowly pivot while putting one leg in
4)if all else has gone well, swing final let into car.
by the way, when you take it in for service put the seat-back up and the seat all the way back before you get out. the techs will appreciate it.
