I have a 99 grand prix gtp and I hooked up a new stereo system in it about a month and a half ago.. in that month and a half my car has died 4 times.. i took it to the dealership after the first 3 times it died and they were not able to find any problems with the car.. they tested for parasitic drain, etc.. found nothing
my stereo system includes an amp, new hu, and a sub.. im pushing about 800w on stock electrical..
any ideas?
