Exclamation system blowing spark plugs?

i have a sound system running off a 1200 watt amp 12' sub pioneer 3000watt and running new speakers for the doors as well pioneer but I just realized with my friend after I installed my hid light kit that my spark plugs are going out and we have came to the conclusion itís because of my system pulling too much power and actually causing my hid lights to go out and also my system to shut down any answers or anyone gone thru this problem?

the system will not cause failure of HID or spark plugs.

the system can shut off due to a drop in voltage. what is the battery voltage when this stuff shuts down?

a drop in voltage can be caused by several factors:

1. poor grounding and wiring connections. you can post pics of your connections at the battery and amp for power and ground for evaluation.

2. weak main battery. how old is it? what voltage does it sit at when the car is off? has it been load tested? has the alt been load tested?

3. ELD. the ECM monitors ignition load through the ELD and will shut off the alt field current when the load is low. the ELD does not see the extra sound system.
