anyway head unit is the radio/cd player in your car
i dont think i would change it in mine only cuz it flows so nicely wit the stock...
I do think imma get the oem mp3 player tho... becuase currently in my car i have a clarion mp3 headunit and i can't go back to cd's after the ease and abundance of music with mp3's
I found this website very useful
I was looking to upgrade my stock system with some highend stuffs. morelike I was looking for a bracket for a new alpine deck that would fit in storage compartment and accidentally found this site. I'm sure many of you find this interesting. Btw I finished my system set-up and the car sounds awesome @ approximately 1800watts total. I'll have some pictures up soon when I get my optima battery and some caps. my instrument goes crazy even at 1/2 way blasted. thought caps would cure but needed extra battery to run my system normally. Oh and I made my own bracket with a mdf and some vinyl for clean finish.
