New Civic EX Leased - Audio Questions
 

I've just leased a 2015 EX (Canada) model. It's one with 6 speakers (4 woofers and pair of tweeters). The only thing I am thinking of doing to it (because it's a lease), is something to upgrade the audio.

Is there any worth to even think about simply upgrading the speakers in the front (tweeters and front speakers) without adding a new HU or amp? Any opinions are appreciated.

I know I can add an inline amp that brings the level up without changing the HU itself. But I prefer not going that route.

If I just upgrade the front 4 speakers, will I get anything improvements? Not much?
