I'm here with a question.
My latest project is a RPi headunit/car computer. I've worked out all the details expect for a way to connect my RPi, with decent audio quality, to my speaker system. My car has 4 speakers, 1 subwoofer and a 600w amplifier which currently only drives the sub bridged. I would like to completely remove the current crappy noname radio and replace it with the RPi and touchscreen.
So my question is, what is the best way of doing this?
Below I have posted my idea, but I may be way off on my thinking:
Here is a diagram of what I envision.
Here you can find the input side of my exact amplifier.
Here you can find the output side of my exact amplifier.
Here is a similar sound card as the one I'm looking at.
(I would probably end up replacing the 3.5mm jack ports with RCA, or just buy 3.5mm to RCA adapters.)
I should add that I am not an audiophile, all my music is in mp3 form so the highest of quality is not important. Though that doesn't mean I want to listen to shit music either.
Cost is important to me as well. I don't have much to spend and this is going to end up being a long term project anyway.
Or perhaps I should use a USB DAC, like this
, and split the left and right into 2 so i can have front and rear connections on my amp? It seems like a lot less trouble, but the price is a little higher.
