I've searched and searched. I've found BananaGS's installation instructions. I've found about 5 or 6 different unanswered threads asking about stock wiring information. And I've come to this conclusion. There are a lot of confused people on this subject. Depending on which thread I read, I need the 70-1761, 80-1761, 70-8112, or 70-8113 Metra wiring harness or some combination of them. But from reading BananaGS's site, I'm even more confused. Might be because I have a GS300 and he has a GS400 or there is some year difference?
So I have a new stereo and I will be bypassing/removing the factory stereo, cd changer, and amplifier in my 98 GS300 with the Pioneer system. I already have the head unit out, but haven't started removing the rest of the system until I have the correct harness(es). I will be running the corner speakers off the head unit and removing the old sub in the trunk and adding a seperate sub and amp in it's place. I'm guessing I need to run wires from my new head unit to the connectors where the factory amp is located and then attach a wiring harness there, correct?
Simple questions:
What Metra wiring harness do I need to bypass the factory amplifier?
Are the colors of the wiring from BananaGS's site accurate for the 98 GS300, or are there any discrepencies?
If I wanted to keep the stock sub while I build my own box for my own subs, what is its max power handling?

Skip the harness and just tap into the stock power and ground wires by soldering. If you are running the mids and highs off of amps, you should run larger wires to the doors anyway. If you need any more help, I have done this myself and helped many others.

1. Not sure
2. Not sure because I used the Non-Nakamichi PDF file running around. I have it if you need it.
3. Depends on if your system is setup properly. I run 150w RMS to mine and it is still kicking.

Okay, that kind of helps. Yes. I'd like to see the Non-Nakamichi PDF that's floating around. Afterall, I have the Pioneer (which I believe is not a Nakamichi
