Car electronics randomly restarts?

[LReyes66]

Ok so since this past weekend, my car electronics like my pioneer headunit would restart randomly. The head-unit would restart, some lights on the dash would blink, and if headlights are on, they would also flicker/restart with the car. Sometimes the electronics would restart once randomly and be fine. Other times it would restart constantly a few times before being ok for a while.

I installed the pioneer 3600bh touch screen headunit at the end of January using crimp caps, so I thought it might have been a loose connection. So yesterday after work, I decided to recrimp the caps to make them tighter and/or replace any loose caps with new ones. I thought that may have fixed the problem because it didn't happen once on my way to work today, but when I had lunch with my g/f it happened. It happened once before we ate and another time after I dropped her off.

Im kinda stumped on whats causing it. The engine itself doesn't stop but the electronics act like the car is starting from "on using the battery" to actually "on with the engine" because the lights blink and the headlights flicker/restart.

Heres a background of my car that may help:

At the end of January after I installed my headunit, I took my car to a bestbuy so I could have their autotech install a 4 channel JL audio amp to power my after market speakers (kicker and pioneer) since I don't have a garage and didn't feel like running the wires. I already had a kicker mono amp powering a 12" kicker sub and had used 4gauge power wire so I had the guy hook up the 4 channel amp via distribution block. I had 0 problems with my electronics when I picked the car up.

I just ordered new HID 6000k bulbs to replace the ones I have cause the left side light really dim compared to the other. They are powered by plug n play DDM HID ballast... thought id mention it cause they could cause a short somewhere? idk.

Facepalm.

Idk why I didn't consider checking the battery terminals but I went to my Car (at work) and checked the battery terminals n the negative cable was real loose!

Another facepalm.

I suggest you check the battery terminals... and post a pic of the G/F. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
