Its not even that complicated. Just remove the black plastic piece right under the fascia, mount the neon (double sided tape ones) to that, replace black plastic and its hiding pretty well behind the bottom part of the facia.
Experiment with it, you'll see what i mean. I did that with a 12" neon and it reflects off the intercooler well. I could have fit a 16" to 20" easily in the same spot.
Dude its defintely not impossible...takes a little engineering.... i used 1 9" neon rod it cost like 12$ i wasnt paying 40$ for the led's..and i think it looks great at night
And to do it....it might sound ghetto but you gotta wiretie it to the grill....and to get it up there its really easy to do....get your car either jacked up or use ramps, and undo the 4 bolts( i think) and place it up there...
