I recently upgrade my stereo after planning for a long time. I ended up with a set of Morel 6x9 components in front and put the tweeters in the dash location where the little 3 inch ish speakers are, and put in morel coaxes in the rear. I used a sub box from Rodney’s boxes that installed under the center console that came preloaded with an 8” Kicker solobaric. The trick is getting it all to work with the stock head unit, because short of replacing with the super expensive Alpine Restyle headunit, you lose too much on the way of all the functions outside of the audio. I found a video on YouTube from the 5 star audio team for a 2014 Silverado or Sierra. I copied their setup and got a PAC unit to convert the signal to flat, then went to a Rockford Fosgate DSP, then to my amp (scores a good deal on a used Alpine PDX V9 on fleabay - 100x4 + 500x1 for the sub). Happy to share my experience. I’m still messing with it, just got it done last weekend. Sent from my iPhone using Tapatalk
