Subwoofer Wiring Views

[m4rky]

Hi All

Your veiws would be apprieciated as I am installing a Pioneer TS-WX11A amplified subwoofer for a friend. The installation looks pretty simple but I have come across a wiring issue . I am wiring the amp inputs from the front speakers at the rear of the head unit and obviously the instructions with the amp suggest connecting the +ve speaker wire to the +ve amp input wire and -ve to -ve

Unfortunately the amp wiring is not marked +ve or -ve which is causing my dillema? I have tried to folllow the wiring back to the plug at the amplifer, but there are tiny resistors in the line which are confusing the issue for me even further.

Am I looking too deeply into this wiring or is there an answer.

Thanks all

Update

Its ok I've sorted this now ta - had to cut the loom open but as I suspected the marked striped wire from the amp was the +ve. It was confusing as these wires go through a crimp and change to an unmarked wire - strange but true!!
