Looking to get some ideas on some premium components for a custom build. I'm a trainer for a trucking company and I take students out on the road for 6 weeks all over the US in a sleeper semi-truck ( Kenworth T680 with 1400 watt inverter )
From what I’m seeing the TPA3255 can make for a fantastic platform to build an audiophile system, if done right. Currently I’m using the existing factory 4 channel radio with a Samsung S6 table for Navigation and as the music player with USB out to a USB hub / Topping D10s than to the aux-in on the radio.
I’m wanting to design an all in one case with a 5 or 6 channel system to drive the front (2) 4X6 door speakers the (2) 5 1/4 rear speakers, and add a small subwoofer under the front seat or both front seats. There are a few places I can install the case in the semi-truck, so I have some flexibility there. I’m thinking under a cabinet in the rear of truck would be a good location.
I know speaker sizes suck ....... it is what it is......Enough of that….. Here is a list of the items
Case
1 or 2 cases, would prefer all in one case.
If need be add copper shielding of components.
Rasberry Pi 4
As Audiophile Player
Player Controlled by Samsung S6 Tablet
Why Raspberry Pi? Android USB audio driver resolution limitations.
USB DAC
External Power supply
Interchangeable Op-Amp would be a nice addition
DSP Board
Up to 6 channels
TPA3255 Boards
What (3) 2 channel Boards?
Dr Mordor Boards?
Power Supplies
Linear or Switched?
Extras
Maybe a Custom Head unit - single din slot in the dash with custom milled/CNC aluminum plate with Arduino board to control volume/Play/Next Previous track/Pause and music spectrum display.
Controls
Ability to Fade or turn off the rear speakers when someone is driving and the other is sleeping in the rear sleeper of truck.
The goal here is the ultimate custom sound system that can be modified, changed and updated in the future.
I also am considering paying someone to fabricate and assemble some, if not the entire system, as I don't have much time off from work.

I've been waiting to see some reviews in diyAudio of the OSA electronics Dacberry Amp^2, but haven't seen anything recently.
DACBerry AMP2
I may just give it a shot. It integrates directly with a RPi, has four channels, and DSP with GUI. I think it's based on TPA325x? A few of these and some RPis may fit the bill for you. Lots of options. And this could cut your costs considerably (no extra DACs or DSP boards, volume-priced laptop bricks for power supplies, etc.). You could control everything from tablets or phones, possibly not needing the additional head unit.
Your project sounds interesting and fun! Keep us updated.

Nice compact design but I'm looking for more of a audiophile quality on the the amp.
After thinking about it for a bit more I think would be better to use a Intel Nuc for the audio player.

Get the Shui Yuan TPA3255 for this kind of project, just add the mods I made. The module sounds great and very compact for you need.
