Car audio question 05 GT

hey I just got an 05 GPGT and I'm putting the audio from my old car into this car

x2 12in MTX 5500's
Alpine ida-x001
Kicker 750.1 amp
Profile Baja 600x4 (cheap but has worked great for 4 years)
Tsunami 10 farad (kicker)
Tsunami 5 farad (profile)
Optima redcap
this is coming out of a 93 old's 88

I bought the Onstar bypass for aftermarket radios
I also got a 160 amp Bosch alternator to replace oem
I am also going to do a second battery in the trunk


my question is..

This car has a lot more advanced electronics in it is their a huge risk of me frying anything?

Yes there is a chance you will fry something, and dont forget about your relocation kit you will need.

I've never been a big fan of aftermarket stereo's. More problems then they are worth.
