Looking for peoples advice/thoughts on an output stage for a headunit I am retrofitting. I recently found the stock headunit for my R33 skyline and out of boredom decided to remake its mainboard to include all of the functionality of modern units while maintaining the looks. I've got a fair bit of experience with data protocols and digital communication in general, but almost nothing with analog signal processing. The UI/display programming is complete, which leaves me with the audio stage to deal with. My original plan was to run the output of a DAC through various digitally controlled analog circuits. I'm now thinking that noise could be difficult to isolate in a vehicle with dirty power from an alternator and a very small form-factor. Would it be a better idea to manipulate the bitstream pre-dac and then do minimal analog signal processing pre amp, or just stick with the original plan of keeping it all analog? I would want eq, low pass, high pass and volume stages (sub amp/speaker amp) and I already have everything to do so with analog ICs. I was just about to start circuit design, but I figured id get some second opinions first haha.
Thanks for any advice/help! It is much appreciated as I am very new to diy audio in general!
If anyone is interested I can post more info about the drivers I made to accommodate the original front panel, but its pretty boring lol
