SOLVED! No call sound through speakers after install.

Hey guys looking for some help with my 2015 tacoma. I recently installed a amp and speakers with a RCA converter so I could keep the factory head unit. Ive done many installs before so everything went smoothly.... until today. Ive had it finished for a few days now and the speakers all work great and sound awesome. The problem im having is that now when I make or receive calls the Bluetooth is working but theres no call sound coming from speakers. Im hoping I just missed something simple but would love any tips if people have had this issue before. I know I wired the converter to the correct wires for the 4 channel wires out of the deck and power and ground. that's why im confused now. Would love to know where to find Good wire diagrams. Ive looked online but didn't fine details on the other connectors. I hope this makes sense and isn't hard to understand.

Thanks Tim

 

The same thing happened in my wife's car. It ended up being that she hadn't done a long overdue software update and her Bluetooth sound was basically being help hostage. Maybe???

 

Yeah I was thinking about that today and am going to call Toyota and ask if there is a update. Just the timing of working before install and not after makes me think its install related. But thanks for the advice I will call them ASAP!

 

This was phone software not the head unit. Good luck.

 

Oh that might be it too since I think I have one. Will give that a try. Thanks!

 

Fingers crossed!!!!

 

An unlikely, but possible scenario is that the BT uses the front speakers for sound, and running the front signal wires through a LOC and amp messes with the BT signal.

 

Thanks. I actually had a co worker tell me the same thing. I looked at it this morning. I believe it does go through only the front channels Cuz I swapped them and it worked. Now... I also discovered that in my lack of sleep while installing it I left the amp switch to only 2 channel imput. So was able to flip that too witch helped.
Thanks for all the help guys. Glad it was a simple fix. I was worried it would be a problem in the dash.
