Thanks for the info, I did search before asking, there is a lot of info for the 80 but not the 100. I have been thinking of going with a the JL audio OEM clean sweep interface , alpine pdx-5 channel amp, JL Audio C2-650 Evolution C2 Series 6-3/4 Component Speaker System for the front and JL Audio C2-650X Evolution(tm) Series 6-3/4" 2-Way Car Speakers for rear. My main issue is what to put in the sub location. I do not want a free standing sub box.
JL amps are pretty good but way over priced. heck all of their stuff is. Honestly look at the ARC Audio KS line of amps. Also for speakers look at Image Dynamics, Hertz, Hybrid Audio Technologies and even the Polk Audio MM series. The Polks are great bang for the buck speakers.
Personally I would stay clear of the Alpine amps. being around audiophile people and have installed systems that cost me almost as much as my 100 I would go with the ARC amps. Anyone and no one will argue these amps as being some of the most clean powerful amps at exceptional prices. Robert Zeff, who is a genius in the amp word designed these amps and they are just amazing. i think the KS300.4 is around $390 as a 4 channel amp and is 90 x 4 but that is pure clean power. May be more like 110+ watts per channel. I'm bridging my KS300.4 to the front Hertz speakers to give 350 each.
As far as the stock sub location just forget about it. I have met with several high end custom installers and that area is hopeless. Anything you so put in there is going to sound like complete garbage and will be a waste of money.

In the high end audio world JL is hated. They make great stuff but there is stuff out there that is just as good but at much better prices.
I use their subs and they are great.
There amps are good not great. Strong and clear but still overpriced for what you can get from other makers.
I hate JL speakers. To me they are verity lackluster. The C2's are good for the price.
I have heard the Polk MM 6.5 components and I was very impressed for what they are. I think I may put them in my wife's Suburban if I do not go with the Hertz HSK 6.5" components. Can be found for about $175 a set. Fantastic price for the speakers. The Hybrid Image speakers are a very very good speaker too.
I know you don't want to and I don't either but serious;y consider replacing the HU.
