Nice build!

The use of the USB-dac would mean that you take the sound from the cars OEM USB? If so, you would need to tweak the Head units firmware?
Yes exactly. You need to access the headunit operating system and edit a config file

Alpine PWD-X5 and SPC-17 speakers

I've finished my audio project.

My car is brand new so I wanted to stay close to stock for the warranty etc. Keep the original wiring for now and use the stock head-unit as a source with DSP and amp behind that.

I found my solution in the Alpine PWD-X5 + SPC-170C + SPC-170 combination set. Bought the set for just 4000 RMB (510 euro) and added a dedicated Mazda cable. The set is a DSP/Subwoofer/4CH AMP in one. and I opened it up and the components chose are solid. The speakers are average but highly efficient and a much desired upgrade over stock. I will replace the front speakers with the SPS-171C soon. They have better crossovers and are just better build in general.

More impressively was all the isolation work that I've done.

How did you wire the tweeter?

trunk needed sub bump! Robert Fostgate Punch 12" P3 2-Ohm DVC Sub woofer. They are wired for a 1-Ohm load.
I can not take credit for the upholstery as that was done from my freind that own his own upholstery shop. The theme for the interior was mine and he and his crew made it reality. The sub-woofer unit is powered by a Rockford Punch P1000X1bd mono amplifier pumps out 1,000 Watts into a 1-Ohm load.

I honestly could just copy it over here and rephrase it to emphasis the 3 before the 6 but idk if thats overkill vs just providing a link. I'm sure it would make more people aware at the least since not everybody checks multiple Mazda forums.
