My opinion is changing the HU first will give the most noticeable change and is the best bang for your buck. But, changing the speakers is nice and can really be impressive if down the road you switch out the HU. At that point you should notice the biggest change (with the exception of adding a good subwoofer).
Ok cool...thats what I am looking for. I am probably going to change for a good head unit first. Maybe its me but the treble on the stock unit does not seem to go high enough for my taste. The system is all bottom and mid sounding.
