Does anyone remember the model numbers of any of the pioneer head units that were designed to be used with the GM-120 amp?

I'm interested in the ones with the large DIN type connector that plugged directly into the amp.

Must have been some exotic or maybe overseas unit because I've never seen any pioneer decks with din... I've been paying attention since the early 80's, maybe those were older

I have a dead KEX-50 here with the DIN plug. It's one of the later tuner/cassette units with a numeric display. I have an older analogue tuner, but I can't remember the model number.

Edit: I think my head unit was a KP-7500 or similar. Anyway, check out this brochure for more model numbers. Pioneer car 1980

Had a ol Pioneer GM-120, the series started with the KP designation...like KP-366 or something like that...I think it was a three digit number, perhaps a four digit after the KP, its' been a long time now.

I'm not sure it's a true DIN plug. You can see the plug on the following page:

Thanks. That's all I needed to find the information I was looking for.

That almost looks like an external audio or control plug, kind of huge

i'm kind of curious about these, too...... i have an old gm-40, and a kp-500 head, and i would like to find some way to make them work together. does anyone have the wiring, and or pin identification?

 

[Perry Babin]

I found the service manuals for both of them. It may be possible to take the input to the amp board in the KP and send that to the input of the amp.

well, now i have another question, lol...... i googled the amp, and found an old thread on this site http://www.diyaudio.com/forums/car-audio/38000-pinout-pioneer-8-pin-connector.html and the input signal to the amp is small red/white wires, which is curious, because the only thing i could see as speaker output on the head is really small(22-24awg solid) and over 3' long in red and white, or possibly the green and grey with the red and black, and the speakers are negative ground. the red and white wires look like they may have been added by someone. anyways, are you saying you have the service manuals for both of mine? or yours? and, can i get the wiring info, please. i think i may put both of these back into working condition as a pair

Email me if you want the service manuals.

The speaker level signal will be too noisy and too high for this amp. That's why I suggested feeding it with the signal that feeds the amp board in the head unit.

I think it was KP-4500.
