I believe the system is the same as my 2012....I replaced all 4 with entry level Focals. It's an improvement but unless you add a small sub bass will still be weak as 5x7/6x8 are not going to push much bass. It's a huge improvement just to swap out the oem kazoos and the time/$ was worth it. I'd try that and see if you need to go further by adding a sub later.
