i have a 99 mustang gt, auto,allright need help here, i recently put a 200 amp alt in my car because my factory one went bad due to previous owner installed a stereo system in my car, i have 3 jl audio 10 inch subs, anyway i do have a inline fuse from my amp, so yesterday i had it on the highway for the 1st time and after about 25 min of driving my theft light came on and my car shut down, i came to a stop and restarted it and it did it again like 10 min later, so im thinking the new alt is overloading my computer or something, anyone have any idea whats happening here? i can give more details if anyone asks more questions, thanx
