I upgraded my stereo by changing internal speakers and adding 4 channel amp along with adding a second amp for aftermarket subwoofer and now am unable to use bluetooth. The phone links up but no beeps or voice prompts from the system. Any ideas on how to resolve this issue without reversing the process?

 

how exactly did you wire it

 

You must have removed any signal going to the center speaker. Handsfreelink uses the center speaker only I believe...
