Help identify audio wiring harness - base USA X3 pins. - XBimmers

lair12 · 02-03-2013, 02:14 PM

Attached is the wiring harness pairs and colors for my 2012 12 speaker hi-fi system. Can I get help identifying which wires are for what, please?

I assume that pairs 10 and 11 which are thicker are subwoofer output...is this right? I assume that 23, 24 and 25 are 12v power, ground and something else.

That leaves pairs 1 through 9 as wires for the left front input, right front input, left rear input, right rear input, front door left speakers, front door right speakers, rear door left speakers, rear door right speakers, and center channel speakers.

Can I get some brainpower for confirmation of just what is what before I tackle my possible upgrade?

Probably not a good assumption. Why would you think the thicker wire is for woofer(you don't have a subwoofer)? More than likely the thicker wires are for 12v and ground. In this post I wrote that I think the woofer wires were blue.http://x3.xbimmers.com/forums/showth...ghlight=woofer

The thick brown/white and red/yellow are for power and ground. I do have two mid-bass/subs under each seat and have been told that the stock amp is 5 channel at 20W and 2 channel at 40 watts for the subs.

Take a look at this thread. It shows a picture of woofer connector. It looks as if the woofer wire maybe thicker. Looks like black or brown with red. Don't know if right or left. Like I said I think the right side was blue. But again it was a after thought to note the color.

I have replaced the two subwoofers under the seat and can confirm that pair #10 goes to the passenger sub, pair #11 goes to the driver sub, pair #1 goes to the passenger front, and pair #9 goes to the passenger rear.

Still need input on what the other pairs feed or are sourced from.
