Big Audio, Suspension, and Axle upgrades

Things have finally settled down and hibernating season is upon us! for me it is time to start my BIG build. I am very fortunate to have purchased what i like to call my DREAM G! Performance wise i could not want anything more. But i am a huge audio head and i like having a beautiful sounding system, with Crisp Highs, Vocal Mids, and Deep Lows. I have personally always loved alpine and i decided to go again with alpine in this G. With the exception for my mids as i had alpine type S 4" in my last G and left a gap on between the door panel and door frame. I was told an interesting idea by a local future shop installer, to replace the 10" pancake subbwoffer with 2 6.5" Components cant wait to see how that turns out. The center 3.5" i will leave in the dash hooked up to the factory system just for the bluetooth and navi. I know the sound will come trough the audio processor for both, but the factory audio system was designed for noise cancellation and the person on the other end wont hear the echo the Alpine system will cause (alpine system will be muted during a call).

Also i have always loved air ride and personally think with all the speed bumps, speed humps, inclined, and declined driveways it is the best option for me living in Vancouver. After Careful research and advise from my doctor (liberty walk GTR JJ Dubec) i have decided to go with Airrex Struts and Accuair for management. My Doc said in his opinion the struts improved his ride on the GTR a lot. So that is why opted for the Airrex struts over just get UAS over my KVW3's. The reason why i chose Accuair and not the Airrex management was honestly and simply because i want to control my ride height from my phone rather than a remote controller while i am outside the vehicle.

Lastly recently my Axle shaft broke. I got some wheel hop and that was that. Went to my local mechanic who works at Canadian tire, he has recommend me a local shop that makes custom Axel's. I will be going to get a quote for 1000hp rating just to be on the safe side. Also just in case for any future engine modifications. I will be putting the entire build on here below i have listed what i have ordered and am going to start putting in over the next 5-6 months

I am always open to better suggestions or ideas, I really do want to make this one of a kind thanks for your help guys!

Then the imaging of your front sound stage sucks. When it's right, back seat listeners will still be able to clearly hear the music just fine coming from the front and not from behind them.

Besides, if they were important they'd be in front so who cares what it sounds like to them.

Not sure, like I said I don't want anything too crazy... Thinking About putting a sub in the back, in addition to the nose system. But is like to upgrade the nose system too... I had Rockford fosgate punch series in my RSX and it sounded pretty good... But the stock speakers in it kinda sucked to begin with... So idk what to do with the G.
