Hey guys, I've searched for stereo upgrades and always find the SCrews... I have 2013 reg cab long box XLT. Was wondering if there was a signal out wire present somewhere to hook to an amp rather then crappy line out converters from a speaker. Didnt know if wiring harnesses could be the same as the fx4s. Seeing as though the fx4s didnt come in reg cab I have my doubts.

I didnt want to swap the deck out yet. Enjoy my free sirius for a few more months. Lol. Any other ways? Pics are always welcome

And if you have swapped out your deck, was there a seperate box to keep the factory audible sounds and to leave power until door was opened?

Thanks for any info.
