I had Jensen Triaxials in my Bronze Chevelle with a Pioneer Supertuner II years ago in high school, then I threw a cheap amp on it with an Audiovox antenna booster. The wiring was fairly simple.
It was definitely an upgrade to my Cheap Audiovox FM converter.

yes those speakers

These are not normal speakers, they use a push pull principal..
Here is the schematic of the speaker (yes, it is a fully active speaker, it requires 12V!)
Please note C1 in the schematic. It is most likely dead and will need replacement. The D45 series transistors were made by Delco originally and were really excellent for their time.

A high-efficiency loudspeaker with a split voice coil and directly coupled push-pull audio amplifier circuit, especially useful when energized through a single-ended, low voltage, external power source to increase the output of a relatively low-power audio amplifier without undue distortion.

A loudspeaker with an overlay or bifilar wound split voice coil, a coil for driving a higher frequency speaker such as a tweeter, and a push-pull audio amplifier circuit directly coupled with the coils. The configuration of the split coil provides two coaxial voice coils that produce a...

So on the wires I have shown..for the front control and the speaker wire also..can you tell me the color coded connections going specifically to where?.. Please..
I will have to look at the back for the model number. I used to re-foam speakers and they never turned out very well. Now I just buy speakers from parts express, great speaker for cheap. When my Marantz 12" woofers foam went bye bye I bought a pair of speakers from them for $32 a pair, have to tell you they sound better than the originals by far and seem to take more power also.
My stock speakers work great, but I can't hear them.

The whole hunt for the MindBlowers..wasn't for power/or quality..Mostley to find something that is very hard to find..If not impossible..to go into my 1972 Chevelle period correct equipment
How would anyone know if a speaker is "period correct?"

When Chevelles were teenager cars air shocks, loud speakers and Cragers were period correct.
Agree, but with a grill installed, how in the world do you tell what year a speaker was made ?
6X9 speakers look all the same to me. Just wondering.

When I was a teen the 1972 Chevelle as well as other Muscle cars..most of them had these types of speakers..When I said period correct..not 1972 but speakers you might have had IF you had a car like this in the 1980'S

I did. Poor thing had its dash cut for the radio (Pioneer SuperTuner II) and shag carpet on the rear shelf with Jensen Triaxles. She is all back to normal now living the good life. Dash was replaced in the late 80's with a new OEM Malibu dash.
