Tripintaz- How would this help with the install? I have the factory wiring harness already in there. The trouble is, the previous owner ran his own speaker wire to his amplifier (I assume) The whole audio system is a mess.
I have a wiring harness to go from Subaru OEM to aftermarket radio, it is my understanding that I have to solder this harness to the Pioneer HU harness. Is that right?
Anub- I really have no clue how audio systems/ electrical stuff works. Do you recommend that I wire the speakers up to the HU and just run the Sub from the Amp? Also, my amp gives me the option of switching between 2 and 4 channels. I'll take a picture of it when I take the car apart. That way somebody can explain to me how it works.
