First off, thanks to this great community for advise|support|direction (specially ChrisM101 & Chief_6.7) For the most part I have finished the upgrade on my 2017 1500 Express CC - Non Alpine, Non 8.4 (as Crutchfield refers to it). Just want to share with folks that may try and tackle similar projects. I did not want to go super expensive at this time as I prefer to spend that money on performance mods, but I may upgrade from here later on, and I'm super happy with the results!

I kept the stock head unit and added the following items.

  • Replaced all door speakers with 6x9 Rockford Fosgate P1692
  • Dash Speakers are Kicker SC3504 3.5"
  • Foxbox with Dual 12" Vented
  • Kicker 43CWR122 12" subwoofers with dual 2-ohm voice coils
  • AudioControl LC7i
  • Kicker CX1200.1 (Subs)
  • Sundown Audio SA100.4 (Fronts & Rears)

So the first thing I did was of course replace all the door speakers, I actually did that long ago just so I could have some better sounds then the stock speakers. Once I got all the goods in I started the project. First thing I did was tap the speakers for the LC7i. I tapped the fronts at the HU and the rears at the B pillar.

Fronts at HU:

Forgot to take pics of the taps at the B pillar but there are many threads that reference it here, it was very easy.

After I tapped all the speakers I then ran the power for the amps and the LC7i. I removed the clutch plate from the inside of the cab, behind the steering wheel, and then drilled a couple of holes in it for the wiring. Then sealed it up with some rubber sealant. I could have bought a sealed grommet type adapter but it was too late as I did not yet know where I was going to route those through. But it will work.

Mounted the AMP fuse box to the bottom of the battery to a bolt that I assume holds the box the batter sits in down.

Next I mounted the LC7i to the back cab wall. I cut some plywood to size and glued it to the cab wall with Loctite PL Premium FAST GRAB Polyurethane Construction Adhesive (that stuff works great!).

Then it was time to run the wires for the door speakers. For the fronts, I removed the wire plate that mounts to the door, then disconnected the plugin module and unhooked the two plugged in modules. Then I fished the wire through that rubber hose line and then through a small open space on one of the cab side plugs, the passenger side was way easier as it only has one plug plugged in.

Here is one of the the rears, pretty much the same as the fronts but much easier to get at. The plug in the B pillar has a lower corner space in the plug that the wire fits perfectly through.

This is all the doors finished.

After this, I prepped the Foxbox. Had to install the buckets that come with it, I used the Loctite Premium PL Polyurethane and the supplied screws to adhere it to the box. Then mounted the subs.

Now it was time to get everything connected. I made some more wood mounts for the other 2 amps and got them attached to the cab wall. Then of course I got everything plugged in to make sure it all worked before I mounted the amps and cleaned up the wiring. Once that was all good the fun ensued. Mounted the amps, shorten and cleaned up the wiring and routed it to make it look as clean as possible. Here are a series of those pics.

Note: These are the speaker taps to the LC7i, these needed to have resistors put in otherwise no sound would work. What was recommended from AudioControl was 37 to 5-ohms, 5-10 watts. I went with these 47 ohms, 10W and they work perfectly (I soldered them in).

Here is the finished look with the back seat in.

One thing of note that I found today. When you open and close the bottom seat, the rear rubs against the small indented spot of the Foxbox and it is ripping at the bottom seat liner. That is because the Foxbox is sprayed with Rhino Liner. I'm going to lay down some plastic there so it does not tear at the liner.

All in all this was a super fun project and I learned a lot. In total this took me 2 full days to do, not to mention having to support my clients when needed while doing it. If you are embarking on a build yourself and need some further clarification on what I did or not do I'd be happy to help.

Looks great! How does it sound? I'm waiting to install the same box and three amps right now.

Do you notice rattling without sound deadening? My stock setup rattles quite a bit.

Can you post pictures of the seat-rising spacers?

Glad you got the pictures working. I was really looking forward to checking it out!

Sounds super great! Yea there is some rattling. I will add some dynamat soon, honestly though when it's cranked up I just hear the music. Those spacers are just wood blocks basically. The go down and then drop the seat on top of that and bolt it down. I will show you though.

Glad you got it all in. For future reference, 2 runs of 9-wire would have probably saved you a day of installing.

Looks like a solid install, they have made a lot of changes to that vented box over the years it looks like.
well done

Did you have to tap into the dash speakers to get signal? I am also doing a complete upgrade in my 2018 ram 1500 with 8.4 uconnect. I ram two sets of wires in all 4 doors .1 set back to 4 channel amp and 1 set from the factory speaker wires back to my lcq1. I have everything wires correct and everything is turning on with remote wire but I am not getting any sound from the radio .I have the audio control load generators connected to the lcq1 . I did not replace the dash speakers and left the factory ones alone. Is that causing my issue ? Any insight is appreciated

Someone else posted that the AC load resistors do not work for Chrysler. Try removing them and wire in a 100 ohm resistor per speaker line.

Yeah those AC load resistors definitely do not work, I bought a pair and they did no good. I did get some resistors, that you can see in the above pictures. Audio control recommended that values that I have. And I got them from a local electronics shop

Since the stock HU does not have Pre amp outs, the LC7i makes it possible. You take speaker level into the LC7i and then it gives you rca outs. Great unit I must say.
