I have a 2003 Z with the Bose Audio system. I have already replaced the head unit with a Sony CDX-GT610Ui. I would like to upgrade the rest of my system to get some better qualtiy sound and bass, right now at higher volumes it gets distorted. I am new to car audio so I am not sure if it is necessary to replace all the speakers and get a new sub or just get a new sub. I also dont know if I need new wiring components or not. My question is if what kinds of speakers, box, subs, amps will fit and work well together to get some decent sound and bass at louder volumes. I would like to spend around 600 bucks or so to get all the gear I need then go someplace local to have them do the install.

Can anyone recommend some decent set ups for me and what all I would need to buy to get going on this?

Thanks
