Subwoofer/Amplifier wire colour

[Commo Fan]

im installing an amp and sub in a brothers mates mums VY, and i found that theres a fuse for a Subwoofer or Amplifier but i cant track down what colour the cable is... the fuse is no24 or 25 on the fuse box under the steering wheel and it needs a 20A fuse for a sub or 30A fuse for an amp. i tried using the yellow/red 12V OUTPUT cable but i found that to be antenna power, so the remote was only powered when the radio was on, and not when a cd was playing.... and when i had remote wired to accessories, it worked fine, but every now and then when i turned the deck off, the deck stayed illuminated, and at different times the subs went haywire, so im not fond of using accessories... any suggestions for the Subwoofer/Amplifier wire colour would be great

there is a thread in the audio section about wiring colours and charts think its a sticky if not just do a search
