Yes, you can add a sub.

There are so many ways to do it...

You can do lots of things to upgrade your car audio system. I started out with absolutely no knowledge whatsoever. I learned by going on various forums and websites. Crutchfield.com has a special advisor page that explains a lot of car audio concepts to newbies. I learned most of my knowledge from them.

I started building my system by switching the factory speakers to aftermarket speakers. If you get the correct size speakers then they should fit with no modifications needed. Just simply mount them in the factory openings with the screws provided with the speakers. Sometimes you might need to drill new holes but Crutchfield can tell you if you need to or not. Aftermarket speakers provide a tremendous difference in sound quality than stock speakers.

After you swap the speakers, you can choose to get an amplifier or subwoofer later on (when you have gained more knowledge about car audio). Good luck.
