Well, when the installer finally managed to add a rca converter to the bose system ,after many days, and power up the amp we tought everything was okay because everything worked fine, but like 2 days later when i returned to my city i noticed the amp had the red led on (it was protecting itself) and the sound didnt worked, but then a few days later the escalade check engine sign turned on and the truck shut off completly, good thing i dont drive very fast, so with the impulse and the handwheel very stiff I parked on the side.
We tought it was a gasoline dirty thing, because here the gas quality sucks big time, so the truck worked a couple of days ok, but it stopped again with me driving it..
If i tried to start it right away it didnt work out, but if I waited a couple of minutes it always started...
I took it to the mechanic and he told me that the baterry cable was very loose, so he tighted it up, and sudennly the amp and the woofers started to sound too, and we tought that was the cause the truck shutt off and the sound not working.
So I was good for a couple of days and it hapenned again, so They connected it to their computer and the error codes told that a chip on the pedal was faulty, so they ordered a new one from the cadillac dealer and then the truck started fine but the STABILITY SYSTEM DISABLED sign was on.
So they told me that the truck was ok and besides I had to wait for the cadillac mechanic to came to my city, like I told you the cadillac brand is relatively new in here so they use cadillacs mechanics from other citys...
And i was fine like 40 days when suddenly the truck turned off again, so my dad Send it to the nearest Cadillac dealer, wich is very far from my city like 7 hours, and there they told me that one of the 3 computers was fried, that a big discharge of voltage did it, but they checked the sound and they said that the current was well distributed, but that maybe the sound installer when he was experimenting with the bose system, because you know its very different from a normal stereo, touched or connected something that didnt should and fried the principal computer.... but they are not sure what happened really ....
SO.... my question is did the installer touched sometingh it shouldnt ?
Or did the loose baterry cable fried the computer ?
I didnt have my escalade for 2 months.. but because of that my dad told not to mess with the electronics, so I just want to do it simple things like adding a Optima baterry and things like that, because when If I left something on like the warning lights,but for a very long time, the other day i left them like 6 hours on, oopss, someone gave me current with his car, or I hear my subs with a lot of bass with the truck off like 40 minutes the baterry almost dies completly.....
thank you for reading this long post.....
