Your exact same question you asked is the same I also asked and did years ago. I was told by a few people that I should change Head unit also, others told me I would still eventually change the Head unit. I started Upgrading everything else, Speakers, Amps etc. Held onto stock Head unit for awhile, but time later did go ahead and change the Head Unit. I'm happy I did and wish I had did that much sooner.
