Upgraded my sound from the base six speaker system to something better. I managed to fit a Rockford Fosgate 750-1D and a RF R2-500X4, plus an AudioControl LC2i Pro, all under the front driver seat. My goal was to keep the new audio gear together, and with as short a run for electrical wiring as possible. Clearance is narrow, but still good at the lowest seat position. Total length of power wire is less than 7.5 feet; ground wires are about 6 inches. Only the speaker wire for the sub runs to the back, nothing mounted to the back wall (I need that for other things). Sub volume control knob and remote line run under the center console.
Removing the ANC module / bracket left a pocket area to conceal wiring under the amp locations, while also providing a 10mm frame stud on each side for the amplifier grounds. Front Speakers are REF-9633ix 6x9 & Kappa 300m 3.5 W/blockers at 2ohm for 125 watts, with 75 watts at 4ohm for the rear 96333ix’s. I used hi-level inputs front and rear to the R2-500X4 via a clipped iDatalink bCH3 bypass.
I originally ran an RCA line out from the R2-500X4 pass through to the sub amp. However, this caused some low feedback in the line (the RF amp was likely not designed for hi-input to low RCA output). So, I tapped the rear speaker lines to add the LC2i Pro to fix the issue (the Pro has a ground selectable circuit).

I transport gear in the cab when traveling so I did not want to install an under seat sub box that I would have to move or pull for trips. Instead I built a custom box for a Kicker 10” L7T to replace the folding center armrest. To make sure the box has the correct sized cubic footprint, I ended up having to relocate the entire rear seat group forward 1.35 inches at the frame mounts. I still need to steam heat and work out some leather wrinkles from the Katzkin covers, and I haven’t had a chance to fine-tune the sound system yet, but it is definitely improved.

I’ve nearly finished my silver interior trim delete.
For the life of me I can’t figure out why RAM would leave all that silver trim in a “Night Edition” truck.

Also reupholstered the sun visors to match the Katzkin seats (an absolute time consuming nightmare), after my failed airbag safety decal removal attempt.
