The wires labeled + above are connected to the positive outputs of the stock radio. It's possible that Subaru has reversed the polarity on all of the speakers at the speaker plugs. That will work fine as long as all 4 are reversed.
If you really want to be sure, connect a 1.5v battery across each speaker. + to positive will cause the speaker cone to move out towards the front.
Most of the wires change color mid-way between the radio and the speakers.
....this is the correct color code for the front speakers in my 2003 Impreza TS. I'll post the rear spkr. colour code when I pull those speakers out.
Thanks for pointing out this post SVXdc.
I did a search, but did not find this one.
BTW, I've installed Polk Audio DB650s in the front.
I made my own spacers out of 3/4" MDF.
I sealed the MDF with water-based Varathane outdoor varnish.
I tapered the spacers by slicing 1/4" of thickness off the top, which also angles the speakers up slightly to match the stock built-in door card grilles. No need for longer pins & there is about 1/2" of clearance between the speaker magnet & screw in the window, when all the way down.
I'll post some pics when I get a chance.
