hid lights

Hey guys I just have a question... My Mazda protege5 145,xxx '03 has been having problems with the radio been very staticky (if that a word, ha) when I turn on my HID 8000 lights. I just recently installed a new stereo head unit and HID lights and everything works great, the aux and cd etc...

I just received a DDM tuning HID conversion kit for the H11 low beams. I debated for awhile which voltage to go with and decided to try the 55w kit. I understand I'll have to put holes in the rear dust covers of the headlamps to install and I already took a look at this. I would prefer to buy...
