I have a factory created to location to add a speaker in the dash of my vehicle. It is mid-range. Ordinarily, this would be for a more costly separate amp setup. I would like to tap into the front left and right (before each speaker) and then run both left and right to the middle/mono dash speaker. The regular L & R will be pulling most of the power.  
Any issues feeding he mono speaker? I am not sure what is returned to the integrated amp over the (-) wires. Thanks!
