MOST issues after install!

I have recently upgraded my audio system in my 2008 E92 328XI. It had the logic 7 w/o I Drive. I swapped the logic 7 amp with a Mobridge DA1. My system consists of the following:

Mobridge DA1 to Audison Bit One using Monster fiber optic cable.

Audison Bit One to JL HD600/4 and HD900/5 using Stinger 8000 interconnects

JL HD600/4 to Focal 100KRS components using channel per tweeter and channel per 4"mid. (ditched the Focal crossovers)

JL HD900/5 bridged channels to Hertz Space 8 mid bass and sub channel to 12" Hertz HX 300 sub

Amps are overkill power wise but keep gain low to not work amp much and allow for plenty of headroom.

The x-overs are:
Tweeter 3500hz+
Midrange 500-3500hz
Midbass 100-500hz
Sub 100hz and below

The problem I am having has to do with I think the DA1. The OEM Bluetooth is really quiet for one. The bigger issue is my parking distance control. When I go in reverse the right channels put out loud static. After this the right channel doesn't work unless I reset the Bit One. I've been turning the Bit One on/off from the controller before I go in reverse to prevent this from happening.

Does anyone have suggestion on what the cause/fix to this issue would be? I have searched the forums and Google but no results. It looks like most people use the speaker level inputs instead of fiber optic. It would have been easier and I would have been able to keep my steering wheel controls. I just wanted the purest sound possible and now I have a headache. Any help is appreciated.

Do you have the latest firmware installed on the DA1?

Other than that your crossovers are a bit off... midbass/hi should be no more than 200Hz, and sub should be no higher than 80Hz.

Yes, make sure you are on the latest firmware.

I am on the latest firmware. I am going to give Mobridge a call to see if I am missing something. I did notice yesterday that I don't have to reset the Bit One to get all channels working, I just have to cycle through the sources on the OEM headunit.
