USB Audio out or HDMI to HDMI + RCA Audio for Car Install

[AndroidAdam]

I'm working on a project to install an MK808B into my car to replace my stereo and I am wondering if it would be better to use a USB 3.5mm Audio Out to send signal to a 4ch Amp or would a HDMI to HDMI + RCA Audio out to send RCA's directly into my amp. I'm wondering because I want to have a good clean audio signal coming out and due to my monitor not having an audio out (that I'm aware of, it's a barebone screen). Also the USB option looks relatively cheap around $5-10 whereas the HDMI converter option would be around $35 from what I've seen.

Thanks!

Other alternative option..
Using a 'bluetooth audio reciever'

Somewhere on this site a mk808b user streamed sound to laptop using bt
Anyway.. just a thought..

That actually looks like a good solution, as long as I get good quality sound and almost no latency I am all for it! I found some good reviewed bluetooth audio dongle's for around $24. The only problem then is that they all look to be rechargeable or would take batteries and I would want something that can be powered by car or the MK808B.

Decided to go with the HDMI to HDMI + RCA Audio as I plan on buying a three way HDMI switcher and running it thru that then into the monitor. That way i can have extra HDMI ports for other devices. Build log coming soon!
