- What model headunit?

- Is the buzzing noise coming from your speakers?

- Were the failure / buzzing happening BEFORE the neons were wired in?

- Did you get either professionally installed?

From the manual (http://pdf.crse.com/manuals/3251114211.pdf 4mb) here, it says that 'FAILURE" means that 'the connection of speakers / amplifiers is incorrect.'

Did you change the wiring when doing the neons?

How about the grounding for the neons, is it to a clean spot secure to the chassis?

Is the neon power wires anywhere near the amp wiring? Try moving it away...

nah i didnt the touch the system wen i the neons were installed...all the wires are sent to the engine n the amp is in the booth

faliuer on a sony indicates you have a shorted speaker (short to body usually. the buzzing noise isthe unit telling you someting is wrong.

start by checking your wiring off the radio and then the speakers.

nothing to do with the neon kit you fitted.
