Come to think of it, every ballast I have seen from Philips / Denso / Matshush-i-ta / Panasonic comes in a full metal box with metal brackets. Even the cheaper China made kits that copy this design are full metal jacket enclosed. Is it because this creates a Faraday cage and will provide EMI protection to the other electronic components of the car?

Also, this means that the ballasts should be bolted to the metal frame of the car so that it is grounded, and not simply zip tied anywhere.

Additionally, A great deal of noise may come from the High Voltage lines between the ballast and the bulb, especially if your ballast has an external ignitor. The best way to combat this EMI may be to get some stainless steel hose sleeves from the Home depot or Autozone and run it over the wires..and make sure that they touch the car frame to be grounded.

Food for thought.

heh? I have a DDM kit in my fogs, no problems. But I do get all kinds of engine noise in my aux port when I listen to my iphone music

That might be the EMI crackling it.....

thats not from your HIDs, theres a tsb about that, i think the aux jack itself is faulty.

You elimnate the problem by buying an HID kit with an EMI filter. Talk to xenondepot; CL vendor he will help you solve your problems with proper equipment.

That is not the point here.
Point is why do the big guns make Ballast with full metal cage and metal bracket. That is to provide a level of redundancy when electronic EMI filters start going out. That will happen even to XenonDepot kits. If Philips expects theirs to go, what is xenon depot? At least that is what I believe is the design.

You actually solve the problem by buying a car fitted with Xenon from the factory.

But like I said, that is not what I am driving towards. I am driving the point that you need to install the kit so that it is on the frame of the car, and not zip tied to a plastic part or powertrain cables. That way, in the event of EMI leaks, the Faraday cage will be effective.
