Hey all! Just bought my first brand new truck 3 days ago, and love it! 2011 GMC Sierra SLE reg cab/short box... Want to upgrade some sound...

I have the CD/MP3/XM with USB head unit and was wondering if anyone knew if it has pre-outs for an amp...? I can't seem to find any answers (been searching for a while)... I know there are low-level input converters out there, but I would prefer to use pre-outs...

Perhaps a pinout/wiring diagram as well? Need to know which is the signal wire to turn on the amp...

Thanks!!

Oh Noooo.... :uhoh:

So how do I get the signals I need to a back-of-cab mounted amp, running a 10" sub (none of which has been bought yet)...? Any suggestions?

Well you can buy a pac loc with both or you can buy an amp with high level inputs and then run a power line with a toggle switch on it to the amp
