Installing sub, Need some help

I have ordered a new sub and box for my 2012. I need some help determining where to get my subwoofer audio signal from. I have read that some have intercepted and used the signal from the factory sub and that it may already be low level so no preamp converter would be needed. is this correct? Does anyone know which wire colors are positive and negative? Thanks in advance.

I couldn't get the sub wiring to work for me on my 2011 superduty, even tho it worked on my 2011 f-150. On the superduty, I had to tie in the LOC at the headunit to the front left and right speaker feeds.

Yep, ended up just using the right rear speakers. Turned out great. Thank guys.

BTW, the JL Audio stealthbox is awesome. I have had louder systems before but with limited space this was the way to go. Also, they now offer the 13.5 inch sub in a 2 ohm. I ordered it off Ebay for $749, free shipping and no sales tax.

Another way to get a signal is to obtain it from the factory sub speaker wires using the OEM amp and wiring the two sets in parallel so they don't over load the OEM amp. The OEM speaker is a dual voice coil speaker thus has two sets of outputs from the OEM amp. Soundoffaudio.com has all kinds of sub options and adapters for the Ford SD. I ordered a rear seat sub with two 8" a Kicker amp, wiring, adapters for $600. All I have to do is remove the rear seat and install it and put the rear seat back. I also replaced the rear speakers and the front speakers as well as the front tweets in the "A" pillar with surface mount tweets.
