i m selling the ccfl kit used in computer casing, tested it with my car yesterday, on for 5 hour no prob man, and i think if using sound module will be even more safe for the ccfl..the price is RM45 for the whole set, just plug and play, btw, i may need to modify a electronic voltage limiter since ur car voltage from 12-14.4
will update the final price tomolo, but i think the coltage is not a problem since ur almost all car are not full voltage often, most about 13.+ which are safe for the ccfl..thanks..if u interest can pm me.
