  • Completely removing HU from build

    Is it a bad Idea to uninstall the HU entirely running all music from the computer and using a USB DAC for my analog signal?

    Something like thishttp://www.amazon.com/HRT-Music-Stre.../dp/B0038O4UFQ

    From here everything feeds into a 5 channel amp. Right-Left-Sub

    no, it is not a bad idea.

    many of us run it that way--replacing the hu was my main motivation to building a carpc(for the audio tuning options). overall, it seems that this method has started to be referred to as a 'headless' setup (though technically the carpc becomes the headunit)

    that unit has good reviews all around, the only reason i won't buy it is because i require at least 5 outputs for my setup, and buying 3 units is not cost effective.

      I was wondering about that. The USB DAC has two outputs, for each stereo channel. But an amp wants a seperate channel for EACH speaker. Why is this? Just for more indepth fading options? I plan on feeding the input from the DAC into a crossover and EQ before amping the signal, but how do I take two signals and send it to a 5 channel amp that wants 4 minimum

          the 'best' way is rca y-adapters. best as in cheapest/easiest to install.

          what eq and/or x-over were you planning on using? some models support upmixing to multiple channels, so y-adapters might not be needed.

              I'm planning on doing the same, ditching the head unit for a more clutter free install. I haven't decided yet but I think I'm going to go with this from the store:

                  check nivanov's build thread on his trials and tribulations with that amp chipset(link)-- it woks good, but it does require a heatsink, and as far as i know, mp3car is not selling one with it..

                    what about a crossover with a built in upmixing for multi channels

                          roll down the windows and enjoy it how they used to.

                          actually, i have this accounted for already-- i maintain a secondary input into my amps to provide a workaround in the case of a carpc issue..

                            And headunits break down as well....... especially the higher end GPS ones they seem to have more issues then the basic ones.

                              A cheap knock-off from China maybe! In the F150 (which i totaled) i ran the computer through the AUX input of a Pioneer AVIC-D3 which kept running while i replaced the computer's HDD, RAM, and while i reinstalled a corrupt OS.

                              Granted, the Nav units today maybe more prone to malfunction due to they sophistication but it wouldn't make sense to have a high-end HU AND a computer. All you need is a good single din unit with AUX input. Those are even more reliable.
