Head Unit another idea for aftermarket stereo

[Frost]

hello to all!

i'm Italian, please excuse me for my scholastic English!!!

I have just installed on mine type s 2 tweeter and 2 woofer in the front one, with 2 amp and a sub.

next to the beginning I thought to use the famous one rockford syxty for convert hight imput to preamp, but the result is Horrible.

I would want to install an aftermarket stereo (i think alpine) in the small space under the oem radio in parallel.




i would want to see only the air conditioner temperature on the original display, does not interest the hour or other.it does not import me of the rest (hour, tune ecc)


thoughts are possible?

in order to explain to me better i show a image: (i don't have i-pilot )
