Hi there, I have installed a PA660 in my 2012 Kia Rio along with Polk DXI650 front / DXI650S rear.
The question I have is that the speaker level input harness has a pair of wires for every speaker input but there is an additional black wire that is not described in the product manual.
I left it disconnected and the audio sounds great, but should it be tied to something ?
