R33 Gtr Car Audio Issues

[judasentinel]

I have searched the forum, and the web, to find answers to my issues, but no luck thus far.

I recently installed an aftermarket JVC stereo in my R33 GTR. I used the wiring guide I found on here, and followed the instructions, but there are a couple of issues that have me stumped.

There are two plugs in an R33 GTR - the smaller one is for the rear speakers, so once I connected them to the head unit, I also connected the front ones, but am getting sound only in the front ones. There is no sound in the rear ones.

Do the rear speakers need the factory amp to run them? I was under the impression that all four speakers need the factory amplifier, so if the front ones are running, the amp is powering up, but now I am not so sure. If the amp does have to be connected, where can I find the connection to it? The guide says that there should be a wire on the smaller plug for the amplifier, but in my case, there isn't any wire for the amplifier on the smaller plug. I would appreciate any help in identifying how to find the amplifier wire to connect to the head unit, if required. All other wires are correctly hooked up.

Thanks, guys.
