aftermarket headunit problems
 

i im new to these forums but i have some questions and would appreciate some help


1st. off i have a '95 3000gt base and i tried installing a new headunit on it.
i did some stupid mistakes which costed me some big problems. 1. i did not disconnect the negative charge on my battery before installing. 2. i took out the old stock headunit about 3 days in advance before actually attempting to install the aftermarket headunit. now my car has no batteries. i've tried to jump start it but the alarm keeps going off each time i connect the jumper cables to the car. However, despite that, i can get power to my car and everything seems to be working except the ignition. i cant seem to start it, i hear the clicking but no luck. im not sure what to do at this point, is it a broken fuse? do i have to enter a security code? ( if i do, do i do it through the stock headunit or aftermarket since nothing is installed as of this point) please help me with any of your suggestions

I had one of those before and there is a security code you have to get from the dealership for the factory unit to turn the security off...

Good Luck.
