Recommendations for new Head Unit/Amp/Speakers/Sub

[robbiex1]

Hi everyone,

I have a 2003 3.2S with the Bose system but only in-dash and in-door speakers. I'd like to change the whole system, from the head unit to the Amp. At the same time, I'm thinking of adding at least a Sub and possibly rear-speakers to the rear deck. I know it's going to be a lot of work but I'm willing to put the time and effort in. I'll probably acquire parts over the driving season and do the work in the fall/winter.

I'm starting to read about head units and amps and it's making me dizzy with all the options! I'm wondering if someone has gone through this research very recently and can recommend the parts?

Thanks in advance!
