Define more range?
They both cover the same hertz range. They'd both cover the same distance in a room, if built in the correct box to suit them.

Only major difference between home theatre speakers and car audio is the independence used, and how efficient they are. Home theatre speakers and subs can run off like 15w and 30w, and be loud. Car audio? About 10x that.
I can't remember why that is, but install wise, they both require similar box specs. The theatre ones usually have smaller boxes than car speakers, as doors are fairly big.

As for car audio systems, they aren't limit by currents and independence much at all. Current can range from 5-1000a depending on what you're doing, and how serious you're being. Independence is literally whatever you want it to be (albiet, subs and speakers are usually limited to 4ohm and 2ohm, some 8ohm, some 6ohm, some 1ohm, add dual coils, etc) you can wire them so an amp sees 16ohm if you wanted.
