hids killed my stereo?

I have a 2008 pontiac grand prix ok long story so ill try to give the short version I installed 9006 55w 8000k HID with ballast both low beams with the lights worked great they wouldn't turn on with the light switch set to auto but just switched to on and they worked fine. fast forward a week me and my wife drove about half hour playing music i have a jvc-avx810 two amps a 700watt for my 10" sub and 400 watts for my highs and lows while parking and turning the engine off i see "charging system failure" followed by "service engine soon" on the DIC I quickly blame the lights and swap them out when we get home. .. but the error codes didn't go away. Next day, while driving home from work with music playing and ALL the gauges flat line and the DIC says low fuel I pull over and turn off the car. wouldn't start.. try again after almost calling tow service and it turns over. I drive home. Next day i go to Autozone and have them check the alternator and battery its fine 14.4 volts but the alternator failed once then passed idk how reliable their tester is but i decided since the car is still under warranty I took it to the dealer. This morning dropped the car off this is what they said was wrong "Data communication feed causing all of the warning messages. backed out terminal from JX205 splice and radio is now out of line. Radio should still work but could not verify with out face plate". I took off the screen while it was in the shop. When i put the screen back on the dvd play would not turn on BUT it has aux power as it allows me to eject disc and detach the screen Where the hell is this JX205 connector? I goggled it and find nothing on it. I thought they had gone into my dash cause they charged me $165.00 to just unplug a connector.... nothing was changed checked my fuses all looks good tho i didn't pull ALL of them ran out of day light.

id ask the dealership that told you the jx205 was the issue. they would probably have more info.

hmm... when you have that jvc installed did you buy the expensive wire harness that retains onstar, bose and warning chimes? or did you go the cheap route and just run an acc to somewhere unknown in order to make the radio turn on. if this is the case then it sounds like whatever power source got tapped to make the radio play also had something to do with the lights or maybe it was just causing extra current draw on a circuit that couldnt handle it until it finally flipped out. it also could just be your car, not joking, i have more stupid problems with pontiacs than any other brand of car as far as electrical problems are concerned. ive had several pontiacs refuse to start or lose the programming for the keys or barely start to the point of having to press the gas pedal during cranking so that it will stay running long enough to actually stay running at idle. and all this happens for apparently no reason at all.
