Great idea! Thanks!

The high Power input is designed to handle amplified signal and I think it stayes amplified but not sure. Anywaythanks for thr input. Will suggest it to my installer.

Not all stock speakers are connected to OEM DSP. Only the OEM right midbass output speaker is connected to Helix DSP, which now outputs voice call (and music if not turned down on HU) to the center speaker. Center speaker is controled using HU volume since its the only one connected to OEM DSP...

Couldn't find anything like that.

Yes, it appeared after the changes to the echo problem. My mistake, he connected only the center speaker to the HFL output, not the right woofer.

This is what I did with my system. OK I understand what happened. My installer deleted the center channel and connected one of the HFL outputs to the center speaker instead. Talked to my installer and he will reconnect the center channel.

Thank you, I will try this. Can you tell me to what speakers the nav prompts and directions are routed to? My installer only connected the center speaker and right door woofer to the OEM DSP/AMP, maybe that is the problem.

Tried that, didn’t work. Are your promts working normaly with android auto?

Would appreciate any comments if things are working properly for other users.

Recenty I stopped hearing audio alerts and directions while using Waze or Google Maps with android auto. The music dims as to let the audio in but there is no audio. This does not happen when just connected with Bluetooth. It happens with other ohones connected to my HU as well, so it is not...

Yes. That could be the technical explenation.

For voice calls. Only the OEM AMP+DSP knows how to do the echo cancellation.

You are not getting a clean audio signal, rather a filtered post OEM DSP signal that is cut off so it is optimized for the mediocor oem speakers. Even if you correct the signal with fix86 or something like that it is still filtered.

I'll ask him to draw a diagram when I meet with him again.

Sorry, I really don't know the specifics, don't have that technical knowledge and unfortunately I don't have any pics... All I can say it is very possible if you have an experienced installer that knows his way around these things. From what I understood from him it wasn't very complicated once...

Hi everyone, As some of you may know there is an echo problem when bypassing the OEM Amp+DSP and connecting the OEM head unit to an after market DSP (to get a clean signal and avoid the OEM DSP filtering). During calls the other side hears terrible echo, probably caused by acoustic feedback...

Look at the pics of the A pillar. The gb25 are there.

He connected it to the OEM location, yes it runs through the OEM cable that fed the OEM mic. Very simple install.

Sorry for the delay. Yes, he replaced only the mic.
