Another GEN II stereo thread

[01sapphirebob]

Ok so, I know theres more then a few threads on stereo "upgrades" here on the forums, and I have been looking them over. More often then not, I find myself getting more confused then gaining an understanding on what people have done and what I'm thinking about doing. I currently have an iSimple iPod adapter in it which is working fine. However, It would be nice to get bluetooth and just update the system overall. Growing up my dad was a huge audiophile, even starting his own shortlived speaker company. The stereo in his car was worth more then the car! Unfortunately, all his teachings have been forgotten at this point. Anyhoo, heres what I was looking at doing. I'd love to replace the head unit, all speakers, and the subwoofer. When I was younger, my dad upgraded the stereo in one of my cars with an Alpine headunit and JL audio speakers. The sound was great!

Heres the head unit I was looking at...

I like this unit because of its features, specifically the ability to change the color of the display!

Heres the speakers I was looking at...

Heres where some expertise is needed. Would these work in my '01? What would need to be done to make them work? Do I need to replace the stock amplifier? For the love of god, help! LOL
