From what I can gather the red is 12v live to amp, 2 blacks will be negative for speakers and ground and the other two should be low inputs for the audio. Your best bet is to multimeter for continuity on the blacks to ground somewhere then A voltage test on the red, the only problem I see is that you may not have power on there if you have changed the head unit, I'm having the same problem with my Sony unit, I need to work out what wires are for the amp at the front on the landy.

Cheers. I'm not sure it's how I received it. it's cos of the amp but does it really need that amp if any at all the speakers are loud enough without the amp. Or get another amp ??? Trying to make head or tail of the wiring loom behind the head unit mmm

Ignore what I said, lol I've managed to get mine working. All I needed to do was connect the low input to the RCA in back of the head unit, you may find yours is the same. In the console where the head unit goes I had the 2 din plugs that power the stereo, this also powers the amp and incorporates the remote for the amp power. Now also in the console I found another plug that is about 1.5" long and has 1 red and 1 black wire all I had to do was convert these two to an RCA plug, black being ground and red possitive. Once I had done this I found that there was nothing wrong with the amp it had power but no audio signal. This may be the same for you if not post a pic of the plug you have and I'll try and work out what is what from there.

As I did years ago and posted the info.
All that is needed is two 12v supplies one of which is switch by the headunit, the audio pair and the ground/earth.

Cheers guys I'll check these out
