ok, i just want to test to c if this thing even works cuz it doesnt come on wen i turn on my car or anything. the place i bought it from said to wire it to 12 dc. what does that mean? thanks.

 

do you have the installation instructions that came with it? if not go to the apexi usa website and print them out an read them carfully...........it's important that it's hooked up correctly or you might fry the thing......

dont hook it up directly to a 12v source or you will fry it....

 

im almost 100% sure its wired up rite, its the safc2, so the manuals r in jap, but its the same as the 1st safc. neways, do u no of ne other way to test it other than a 12 dc source. btw, what would a 12 dc source b? thanks.
