Here are few differences:

They are designed to different acoustical enviroments in the mind. 
The main design differences are in wanted subwoofer response 
when designing subwoofer enclosure (inside car is a small place 
and you need to take ino account how it affects bass response).

Car elements are generally designed to withstand conditions 
in car (can get hot, cold and wometimes lots of moisture etc.). 
Home speakers are generally designed for normal living home 
conditions in mind. 

Car speakers are usually designd to have 4 ohms impedance 
(easier to get lots of powerfrom low voltage power supply) 
while many home speaker systems are targeted for around 
8 ohms impedance.

It should work technically. 
Can't be sure what is the soudn quality you get.
