Q: Hey, I have an 01 Chrysler 300m with some serious electrical issues popping fuses 14 and 19 on contact.

After recently doing some audio work in the vehicle - drilled new holes for aftermarket speakers and installed with screws, ran wiring for a subwoofer amplifier, and ran RCAs to the aftermarket head unit installed previously - we started having electrical problems with the car. At first, the car would start, idle for a moment, and then shut off. I assumed this was the security system, until shortly thereafter, I noticed that fuses 7, 14, and 19 were blown. Upon inserting new fuses into slots 14 and 19, they popped instantly, telling me there's a short somewhere. At this point, the car does not attempt to start at all, and most of the interior lights are not functional. Interestingly, when I hit the window lock button on the driver's door, the instrument panel lights would come on, although, this has since ceased to occur.

Extra info - I have since replaced the aftermarket head unit with the factory head unit and removed all wiring related to the aftermarket unit. fuses still pop on contact.

I have opened up the driver's side door panel to make sure I didn't hit any wires when drilling holes and screws for the speaker there, but the wires in the door do not run anywhere near the speaker holes I drilled. Did not check passenger door, assuming it's the same.

I have since unplugged all sub amplifier wiring, to no avail and at this point have completely undone all the audio work that I have touched on this car, but the problem persists.
