I've not paid much attention to the Gen 5.5 lighting. There are a couple good threads here for HIDs
for the projectors. Study them, members seem to be satisfied. I do subscribe to quality componentry. I'd hate to admit what I've spent on (real) retrofitting - likely more than your audio lol. OTOH my headlights absolutely rock. But it's what I like. Mostly I listen to AM talk radio.
As to your HBs, HID is not typically used in discreet HB lights as the HID arc is struck under high voltage and takes a few-to-several seconds to develop, consequently flash-to-pass is considered 'unhealthy' for HID components.
Regardless of what anyone says HID capsules should not be put into a reflector headlight, period. I use a high-end halogen in my HBs, don't remember which, but go here and learn what is current:

And please, stop with the "
W/O spending all sorts of cash" horsepucky. After what you've spent on your 4R and audio, you sound ridiculous. Do it right or stay home.
