When I search with Bing, I get quite a few hits for diagrams for you Pioneer GM-2000 amplifier.

Here is the pinout. You need to solder your own connections.

I’m happy to help further over the phone at https://www.6ya.com/expert/chris_7f7f91eb941fb23f

If you are using two amplifiers used one the amplifier to power a sub woofer on you though frequency the other amplifier willpower the rest of speakers make sure your power wires are separate and the both run at 15 to 20 A

14 or 16 gauge 16 is easier to work with

These amplifiers are universal. You have the speaker positive negatives, power "Red", Ground "black", and remote off/on "blue". Thanks

these are from the actual owners manuel-i used to have this amp also. hope these help
