Hi,

I am planning to use a CDSP 6x8 in my BMW 3-series F30 with a Hifi Headunit.
The OEM headunit outputs a differential Balanced 5V signals that is feed to the car OEM amplifier.

I would like to take this differential balanced signal and feed it to a CDSP 6x8.

I would like to know if a CDSP 6x8 can support differential balanced 5V signals from the BMW OEM head-unit

Hi, did you make any progress with this?

hi champ222, 
in the end my bmw didn't have a seperate oem amplifier. It only had basic audio with  only the headunit with direct high level speakers outputs.

I tapped the signals from the speakers outputs itself.

To get best sound quality and bypass oem headunit completely, i also purchased a 12v Bluetooth receiver with coaxial outputs that feeds into the coaxial input of the minidsp.

on setup, the signal from the oem headunit and the Bluetooth receiver has been summed up together and sent to all speaker

So i have my phone connected to 2 Bluetooth devices simultaneously when i get in the car. 
The phone connects to headunit Bluetooth for all calls and also to the bluetooth receiver for all music.

Thanks for that, i havent bought the car yet, so i dont yet know if it has an amp in the boot or not. Originally i thought it wouldnt, but research is suggesting it does... ill just have to wait and see i guess. Which bmw was it, and where are you based? Its different around the world it seems.

Thanks again
