[QUOTE="Jeffdachef, post: 8611518, member: 650438"] actual audio processing and tuning. Most modern head units have a Quality 24 bit dac way superior to whatever is in your mini pc with a dac. Why? because it allows for tuning. You cant use headphone logic for car audio. Just buying a dac wont help much of anything in the world of car audio because a car is not a headphone. Its a noisy environment plagued with phase cancellation, surface reflections and overall poor audio acoustics. What the head unit does is actually have crossovers, and slope adjustments, time alignment/correctoin along with 13 band EQ or higher, along with having a STRONG pre-out voltage which is extremely weak with pc/pi+dac combos and there's 3 pairs or RCA outputs. Some pioneer head units can run active network mode which is a much more advanced setup where you literally assign midranges and tweeters to do their own jobs and getting rid of passive crossovers from components completely so one pair of RCA will handle midrange, one will handle tweeter and the last pair will handle subwoofer frequencies.. Other standard setups will be front, rear and subwoofer. So yeah you need dedicated RCA channels than handle proper frequencies and puts out strong signals for those frequencies. All is necessary and quite frankly your idea will result in a complete mess because you also lose the ability to time align as well, if you dont know what that is, just look at how your speakers in the car are positioned, your left side is much closer to you so the sound waves reaches your ear before the right side. Time alignment delays the signal so every speaker/midrange/tweeter reaches your ear at the same time creating a perfect centered sound stage which replicates what you can achieve in ideal home audio and headphone situations. That amp is usually 1&2 front and 3 and 4 rear or 1&2 tweeter 3&4 midrange its both stereo left and right. [B]So yeah Head unit for car audio, absolute must. [/B] No ifs ands or buts about it. Its a lot more complicated then you can ever expect when you want a properly done setup and its not possible without a good head unit and head units nowadays are FAR more advanced than whatever you had 10 years ago. UNLESS you just want unintelligible noise that has some resemblance of music then yeah go ahead with your original idea and prepare a lot of RCA to aux and RCA y splitters. [/QUOTE]
