Had one in my '67 Firebird years ago. Mounted it in the glove compartment. It was ok. Had a horrible turn on/off pop/thump. Drove a couple of surface mount rear deck speakers. NO subwoofer! LOL. Audio power was kinda low, so I bought a Craig Power Play booster amp. Helped, but that on off pop was just insane loud now. Much later, I modified the rig to accept an AUX input. Used the MUTE switch to change between radio and AUX. I could then plug my portable CD player into it! Yes, I had the car into the 80's. All history now.
The flash back! I was the Rep for Pioneer Auto when it came out. Sold hundreds of that model! Loved the lockable hump mounts! Service Merchandise was one of my customers. They sold tons of them. Loudness is loudness contour just like home audio. Volume level dependent boost of lows and highs for lower volumes.
The loudness is an equalizer circuit which gives it a boost in Bass and treble when the volume is set low, I had one of these in a Ford Maverick with 6×9 Jensen Speakers. It was great, sounded better than a lot of newer systems.
"Mute" on tuning is a feature each and every FM tuner more complicatet than taiwanese or honkoidal american style pocket radio have, and it's more often called silent tuning, and in older radios it is manually switched with AFC (Automatic Frequency Control - self fine tuning within a narrow frequency range), on newer (over 40 years old newer) switching between air noise silencing and AFC is more often automatic and not advertised. Because more than half of the people are stressed when the radio goes mute while tuning it manually not knowing radio's gone faulty or it's tuned on a station trasmitting silence in the current moment of time, most applications just lower air noise level significantly without fully muting it. "Loudness" is one of several marketing words (super bass, mega bass, etc.) for physiological equal-loudness over hearing spectrum control as defined in ISO 226 standard, and in analogue cirquits consists of one, more often two RC loops connected to taps of the the main volume pot, effectively attenuating mid frequencies far more than high and low spectra to which our ears are less sensitive (a tone correction according to volume level, and the marketing word "loudness" is more correct compared to "some bass", because trebles are also left higher volume), but because volume knob regulates amplification and not the actual sound pressure reaching our ears over the air there's always a switch to turn this correction off when a missmatch occures.
I bought one of those for my first car. around 1979. Dont have it amymore but I do have the original box it came in.

Had one in my '71 Fiat, Radio Shack minimus 7s on the parcel shelf
Those Minimus 7s were great speakers
@@waltergabriel3694 I have 14 speakers in my Mercedes. I think the Minimus 7:sounded better
