It looks good!
Thanks Drift
Whole set up as follows

Critical Mass CM454a front mids and tweeters
Focal IFBMW-S rear mids and tweeters
Focal IFBMW 8" under seat subs
Alpine R10 sub woofer
Audison prima bit 8.9 sound processor
Alpine pdx 1.600 sub amp
Visual Ice E92 sub box
Custom speaker mounts

Headunit is stock hifi. It is routed into the Audison processor that cleans up the signal, splits it into channels and allow the speakers to be tuned

Front tweeters take up channels 1 & 2
Front mids channels 3 & 4
Under seat subs channels 5 & 6
Rear speakers channels 7 & 8
Sub is powered by the Alpine amp on channel 9

The improvement over the stock hifi system is amazing !!!

I would stick to the OEM headunit if you are considering an upgrade. With the right digital processor and speakers, the OEM headunit is perfectly capable and avoids all the compatibility problems of aftermarket

Hope this helps
