JBL HU wiring?

Planning on adding a sub to my system, 2012 JBL HU, and was wondering if anyone knows if it has pre-amp (RCA) outputs for a sub amp?

This would help me plan on what I need to purchase short of pulling out the system just to check....thought I'd ask the gurus here on TW.

Edit for clarity: this is the navi HU incase it makes a difference...anyone?

 

There are no RCA pre-outs on the stock HU's.. You need to buy adapters for that. And the harness for JBL is over 100$, then you gotta get adapters.

 

Most just use line output converters which aren't very expensive at all .

 

Thanks guys...one more question...Is there a place I look to identify the wire colors for the rear speakers so that I can tie into them...or would anyone know this info by chance?

 

I was able to find this info from http://www.modifiedlife.com/2012-toyota-tacoma-car-audio-wire-diagram/ if anyone else is interested...
