I am installing one sub and I found this fourm to find the colours. I found them but one problem. The one one the right door "brown and white positive " is a bigger wire then all of them. The two on the left door are skinny brown/yellow and white/green. The wire on the right door Brown/blue is also skinny. But the brown and white is larger then all three of them.
