If two objects collide on Earth, their kinetic energy is converted to other forms such as light and sound. But in space, it can't be converted into sound energy, so what would it get converted into? And would it be more destructive for the objects in question? Or am I completely misguided?

Heat. 

Depending on size and composition the objects would vibrate, undulate, or temporarily rearrange themselves for a little longer in space if their environment didn't easily remove their excess energy.  Basically, they'd get warmer.  Eventually they would radiate the excess thermal energy.
