definitely replace the head unit for better sound. stock nissan stereo's, especially the base ones have a pretty awful sound to them. my stock stereo stayed in my truck for 3 days while i waited for the dash kit to come in back when i had a single DIN cd deck (now i have a double DIN dvd/nav). after i changed it out, i was surprised how much of a difference it made, even with the stock speakers. i then found speakers and replaced those which sounded even better. later i built a sub box and put in a sub (8" between the rear jump seats, again in my truck not a Z), and was again surprised once i got the channels mixed properly and the LPF turned on and dialed in the amp. it took some work but it was worth it. anyway, start with the head unit first
