Home/PC speakers is a mistake quite a few people in car audio made when they were 16 and "just wanted sound" in the car.
Every single person who has done this will tell you they now feel like an idiot for having done it...and it sounds like utter garbage.
Car speakers and home speakers are designed for TOTALLY different environments....if you think a car won't make it sound different than a house, go ahead and do it. There are different types of speakers for a reason...it's not like you go buy a professional PA system for a van just because it's bigger than a civic....
Hopefully, after actually doing it, one day a few years down the road, you can look back on the experience and have a good laugh
