Time to design the perfect system thanks to my Best Buy discount!

So, I work at Geeksquad and I get the employee discount. I'm trying to design a system for my '92 camry. Currently everything is stock, except the HU which is a JVC - KDHDR30 (the one with HD radio built in).

So far I'm thinking I will go with all infinity kappas. Heres what I think I'm getting so far:
Infinity - 468W Class AB Bridgeable 4-Channel MOSFET Amplifier
Infinity - 6-1/2" 2-Way Car Component Speakers with Woven Glass Fiber Cones
Infinity - 6" x 9" 2-Way Car Speakers with Woven Glass Fiber Cones

So I'm thinking this will be a pretty damn good system. There's one problem I see with this system though. The amp puts out 90w RMS per channel. The components use 90w RMS per channel, and the 6x9's use 110w RMS per channel.

Now what would happen if I tried to use this setup? I really have my heart set on using the infinity amp, since it's so feature rich, but I'm not sure if it would be safe to use it or not. Opinions?

So all the things I hear about Geeksquad are true...

The power output of 90W is due to the amp, not the speakers. The power rating of the speakers is the maximum recommended RMS power you feed them. So your setup will be fine.

Ensure those speakers are 2 ohms, otherwise you'll only get 75W RMS instead of 90W RMS.

On the other hand it's good you are going with components rather than 2 ways up front.

The speakers are 2 ohm for sure, I looked them up on Crutchfield just to make sure.

I bought my first new item for my car yesterday
Infinity REF1252W - 12" Dual-Voice-Coil Subwoofer
I have it wired in parallel so that it's 2 ohms so that I can use my Blaupunkt PCA 1350 amp. Compared to my old 12" Kicker comp, I notice a huge impovement in clarity and a decent improvement in loudness.

Now I have to wait until Friday to pick up some of the other stuff/

That sub is dual 8 ohms. Did you get 2 of theM?

They make it seem like it's that way, but it's actually dual 4 ohm, I have it wired in parallel to make it 2 ohm.
