Working on the system for my 2019 RAM 1500 Laramie Crew Cab that currently has the Alpine system.

Wanting to achieve respectable SQ with as much of a factory look as I can get.

Here is where I'm at right now...

  • Factory 8.4" Headunit
  • PAC AmpPRO4 - optical out to miniDSP C-DSP 8x12 DL
  • Hybrid Unity U5A
    • Power RMS @ 4 ohms: 75w x 4 (door and dash speakers)
    • Power RMS @ 2 ohms: 600w x 1 (subs)
  • Hybrid Unity 6x9 shallow mount drivers for the front doors
  • Hybrid Legatia L3SE - 3.7 wide bandwidth drivers for the dash
  • Hybrid Clarus 10's in an MTI Acoustics custom box under rear seats
  • ResoNix to treat the doors
What I am unsure of is how to handle the rear fill. I never done the rear differential setup in previous builds, but figure I may as well do it this time around since it can be done with the C-DSP.

There is the choice of 6x9 door speakers or the 3.5" speakers in the upper rear headliner... either location will be low and high-passed... so the choice is which is the better placement. My instinct tells me the upper headliner speakers would work better since they are farther back and higher up... but my instinct could be flawed.

I will need the rear speakers depending on which location I end up going with... and a small digital class D amp. Not sure what the smallest amp out there is that would work, but would like some suggestions on which placement and which amp.

Thanks!

Very surprised that there have been no responses....

I bought the 2020 Ram 1500 Limited the week of Thanksgiving. Looks like I am starting all over on the better audio hunt. Thanks for posting. I recognize you from REW's home. I have spent countless hours playing with REW as part of the previous build. Probably time to make another donation as more measurements are in my future...

Congratulations on the RAM purchase... best truck I've ever owned or driven... really really like mine.

While this thread did get ignored, I have another one here with more about the build I did ... as well as a thread over at AV NIRVANA. It was a fun build... and I've still tweaking, but it sounds great as it is now. I'm during the busy season with my business, so I don't have time to fool with the hobby at the moment, but after the first of the year I may find some time.

REW is the bomb, no doubt!
