Well, the problem is you beat on the lasers drive motor and the plastic drive screws since they're not designed to take much force on that plane. That's crucial since the laser needs to stay aligned with the disc.
Some receivers are more robust but as CD's are dying off, they quality is going to drop a bit. My old Alpine was the preferred unit for boats and it still works, although I now only use it for my FM Modulator.
Honestly, I'd consider a receiver with flash memory or capable of reading a USB/Aux input or iPod controller. They are relatively inexpensive compared to what they used to cost.
