why are old school amps worth so much?

I love old school Rockford stuff. I have a Power 1000 and Power 650 I use on a daily basis. These amps were the stuff that a 16 year old, like myself, just couldn't afford back then. haha
When I was a senior in highschool as a graduation gift I was given a Power 300 which got stolen after about a year. Man those were the days....

Recently, I even picked up a broken Punch 45 b/c I had one as a kid. lol...

I got a question? the oldest amp i own is from 1998 - 2000. Would those be considered as "Old School". They're all kicker amplifiers. And my has the first gen "The Punch" 150 amp. Thing is nice!


The 1st gen 150 is old school. Actually 1st, 2nd, and the HD are. 1993 is about where the "old-school" stops in my gear. (and when the HD was phased out) . "Vintage" I would say is in the 1960's and 1970's.

 
When it comes to the Punch 45/75/150 from the good old days, I only like the pre-HD models. I had nothing but problems with a first generation Punch 150 HD and stayed away from any new Rockford Fosgate products until 1997. IIRC, some of the original HDs have problems with electronic components corroding on the driver boards and falling off over the years. Compare this to my pre-HD punch 150 that I purchased in 1989 that is still going strong in a friend's car this very day and it never needed repair!
 
Try a 30 year old telefunken amplifier, it cost around 50 $ shipping from europe or some in usa.

These amplifiers will have a better sound than anything you can buy in the shops up to maybe a thousand $.

I also heard good stuff about the T amp and D-amps , some very cheap from china.

This just my 2cents, I still wish to hear one day a vintage 1950 studio tube amp.
 
I personally have no equipment in my truck less than 10 years old. Eclipse 5441 head, KLW Cathedral for the front processing, HiFonics Cyclops sub amp, Orion 420GT for mids and tweets, Orion XTR10 subs and SoundStream SPL 50 mids and tweets. Not to mention all the other old school stuff I have sitting around. HiFonics Pluto and Cupid, Phoenix Gold M25 and M50, Kenwood KAC921 and KAC521, Kenwood KEC301, A/D/S 320is mid tweet set, Orion XTR1 tweets (made by Peerless), 2 set Savard MR5 mids, pair of JL Audio 10W2 subs and a pair of 12W2 subs, a HiFonics 2" dome mid for center channel, pair of Orion SGX64 6.5" mid bass drivers, Audio Control Epicenter and a 2XS, Sony CDX505RF CD Changer and a single Lanzar LC10S 10" sub. This is just off the top of my head but I think it fairly complete. Recently sold a Phoenix Gold EQ-X 215 and an Orion MBR50. Just can't see buying more new junk when I still have all this sitting around. Of course, working as a custom installer for 4 years and having my own shop for awhile didn't hurt.

I finally was able to dig the dome out from storage. There is nothing on it to say who made it other than part # 95-6569 and "Made in W. Germany"

Thanks for looking! Same thing it says on my Hifonics tweeters...

The brand is most likely "POLYDAX" ...

These are from early 90's, I think Polydax was out of the picture by then?

I was thinking Braun or HECO, maybe a pic would help.

I have a couple pairs of their 6" woofers from '91. I know those were MTX, and their heaviest woofers at that time were Cetec-Gauss.
 
Tim, I think Polydax was still around in the early 90's. The "made in W. Germany" was on the back of the Polydax tweeters. Still have some, but unsure of where they are. Good tweeters for the time. I still preferred the old Boston Acoustic CFT tweeters back then, but the Polydax were much cheaper, and decent for the time.

Here is my newest addition to the old-school collection. (smaller gold amp) . Separate PS and AMP on this model in the CP line...Still looking for more of them if anyone has some. Anyone???

A/D/S was first, followed by a little company by the name of Fosgate without the Rockford back then.

A/D/S started back in mid to late 70's with the A/D/S 2001 bi-amped two way speaker system. 20 watts to a tweeter, and 30 or 40 watts to a 51/4 mid-bass driver. Price was over $600.00 (Circa 1976 of there abouts) It was a power plate type amp If my memory is working right tonight.

I ran Kenwood home amp powered by 12 volt inverter into three way book shelf speaker at that time.

Push Pull transformer coupled amps mounted on the back of Kraco 6X9's were king back then and 8 track tapes were all the rage. Cassette tapes were just a babe in the woods for cars anyway lol lol lol

I was fresh out of high school...🙂

ADS was not the first ,neither was Fosgate and Fosgate had amps and pre-amplifiers before ADS. Got my first Fosgate in 77, along with a Nakamichi dragon tape player using there 12 v power supply.
and at the time we had just started developing subwoofers for Autos with enclosures, back in 78.

The First pull out radio and amp combo dates back to 55 with GM delco , i believe in a Pontiac...... Also Blaupunkt was the first for reference car radios but as as far as reference high power amplifiers
there where a few before Fosgate , the names have slipped me at the moment , but in the 70's it was Fosgate , A/D/S and audiomobile..........

I have never, ever seen a real true class A production amp for a car. Something to do with the 10 to 11% maximum efficiency possible on these types of amps, I.E. 30 watts out has to have 300 watts in while being able to fry bacon on the sinks at the same time also....No matter how you try you can't break the laws of physic's and that includes SoundStream and PPI...

They were all class AB with either elaborate bias drive circuits that kept them in class A for the first ten watts or so ( reference early Alphasonic amps) then switched back to AB. Or they were just plain AB amps biased so high that you could cook eggs on them at low volumes, with big film caps inside the amp to get tube like sound characteristics by using tube like components to do so ( SoundStream Class A and PPI has these large film caps)

Most car amp makers knew from the out set that somethings were unachievable in a car amp, but that never kept them from Bull Shecking the market place though lol lol lol Plus there have never ever been any real federal statutes that made the car amp industry tell the truth about real power, and true design disclosure to the public.
The Home and Commercial and Industrial Sound people had IHF < Institute of High Fidelity" and the Fed regulating what a Watt was and how it should be delivered and tested, and assured in compliance with the Fair Trade Commission < FTC> rulings way back when foreign imports threatened the audio industry... Ahh if they could only see the foreign import issue now LOL LOL LOL Amazing how things change.. But back then a true American Industry was trying to protect its market now who knows...:whazzat:


Soundstream in the 80's made a real and true Class -A amp rated at 25 /ch , excellent amp and sonically quite possibly the best car audio amp ever made.( i still have them ) Not to be confused with there later so called class-a stuff sold in the 90' s which was junk by comparison, same as other brands being sold today under the same banner.....as being " Class -A "

Punch 75, 2 hours, 250339395388

Yeah gold blocks noise...that is a good one.

I don't follow MTX, have a blue thunder pro 754 I should let go but that is not an old amp.

Some old Zapco PS 200...🙂 200286675226

Made in USA Cerwin Vega 700rms broken 180313200409 but has newer style terminals so wonder how old it is.
