The First Amp for Basshead's? 1973 Fosgate PR7000 PowerPunch Amp Dyno Test and Review

Автокөліктер мен көлік құралдары

#AmpDyno #Amplifier #Fosgate
The PR7000 was Jim Fosgate's first car audio amplifier, introduced at the Summer 1973 CES in Chicago, Illinois. This unit was ahead of it's time with RCA inputs, bass and treble boosts and more. Originally priced at $300 USD ($1850 in 2021), this amplifier was truly ahead of it's time. The built-in equalization circuitry would carry forward for decades inside future Fosgate and later Rockford Fosgate amplifiers. Thank you, Jim for your contributions to car audio!
UPDATE 12/09/22 - Jim Fosgate has passed. God Bless Jim's family and friends and we will always remember your contributions and dedication to HiFi audio

    When I was in high school in the early 90’s I would build sub boxes in wood shop. Built a box for 2 Series 1 8” subs for a guy that had a little hatchback. I gave him a money back guarantee. If you don’t like how it sounds then you don’t have to buy the box. When we got it all hooked up the guy had a disappointed look on his face. I asked what’s wrong. He said “It’s too loud!!”. Those 8s were thumpin!!!!

    In 1985 I had a homebuilt ported subwoofer with two 10" Dynaudio subs, driven by an Audiomobile 50wpc amp, in my 2-door Subaru coupe! Rear-deck mids and highs came from a biamped a/d/s 2001 minispeaker system, with a/d/s 300i plates in the front doors for fill. Nakamichi 250 cassette deck, Blaupunkt Frankfurt radio,, and Audiomobile 3-band preamp-equalizer. Man that system sounded good! CLEAN, and LOUD. BTW, several of my DJ friends had 4x8" subwoofer boxes with Phillips "Peerless" woofers that sounded really good.

Over the years I've come to appreciate an old school high quality Class AB lowish power output amp with some high efficiency speakers, a good install and EQ adjustment and think it can sound really fantastic. Massive power output and huge SPL numbers just isn't needed 99% of the time.

I imagine it was being the late 70s and he didn't have any subs just miss and highs 😆. I still think it's awesome to see where our world of stereo systems has evolved from.

It’s seems like they not only offered an affordable high-end amp, but in so doing raised the standard for factory car audio systems by raising consumer expectations.

    Thanks big D that thing is super cool. Cutting edge stuff for '73. Imagine all the folks who felt bass for the first time thanks to this amp (and of course some properly installed 6x9s.) I am surprised at the boost frequencies, industry standard was and still is 100hz/10k hz for bass and treble. Another thing to consider is that even the best tapes and tape decks back then were really only good for 50-15k if you're lucky so the +18 at 45hz/+12 at 20k was basically subsonic/supersonic relative to the available input signals. We've come a long way in 48 years!!

    Like I said, I was born in 83, so my first car was in 1999 and my first "system" was in my 1990 Ford Festiva that my grandmother bought for me, had a Sony Xplod tape deck, a Sony 10 disc CD changer, a bass booster (because I couldn't afford an amp yet), and a Blaupunkt 12" sub in a triangular box. I had a MB Quart split set in the doors and dash, and a set of MB Quart 5 1/2" speakers in the rear deck. It didn't slam, but it bumped a bit and sounded really crisp. Then, once I got a job, I was able to buy my cousin's Sony 4 channel amp (with a sub channel) and I replaced the Blaupunkt 12 with a set of Orion Cobalt 10s and it sounded great. Shortly after that I was diagnosed with Hodgkins Lymphoma and I moved back home to Brandon, Florida. I bought a 1994 Eddie Bauer Ford Exploder and I put the same Sony tape deck, MB Quart mids and highs, a US Amps 125x4 1/4 ohm stable amp (red anodized plexiglass bottom), and two JL Audio 15s in a sealed box. Those two vehicles started my love affair with car stereo systems. Now I have four Sundown Audio SA12-D2s on an Orion HCCA 3k SPLX amp in my 500 whp Accord.

    I installed car audio at “Spinet Music” in east texas from 1976(?) to 1980(?) and owned Alpine head/deck with nothing but Punch PR50s, PR100s, and PR250s for about 2000 watts per side in 1977 (it was installed in a 1975 GMC Jimmy and had 10 speakers in as many holes). We all loved the amps. After 6 months only the 50 watt amps still worked. I started using Harmon/Kardon amps. It might be interesting to note that the biaxial/co-axial speakers were not really available to the average buyer until about 1975. Also i never saw the amp you show here as a single. It was often run as a set of two,three, four or six pushing separate woofer, separate tweeter systems, often with subs. I did a lot of passive crossover setups along with passive EQs to smooth and control the speaker output. We always set Fosgate at 4 or 2 ohms ( 2 amp was when the later amps had a mono setting most often used to push one sub). Wow did you bring back some memories!!!

    The first *quality*, low distortion car stereo amplifiers I ever heard were Linear Power, and Fosgate, around 1981. Followed shortly by a/d/s, Audiomobile, and Spectron. An a/d/s-Nakamichi collaboration produced what was arguably the very first automotive high-fidelity system, the 2001 biamped minispeaker system ---- with the minispeakers mounted on the rear deck, it actually delivered a stereo "image"!. Adding a pair of 10" Dynaudio subwoofers to the 2001, as I did in my 2 door Subaru coupe (around 1984-85), made it a triamped system.

    @@bigdogbrodavepresents6178 , in those early days, I often used Bosch relays to turn the amps on and off. The power interconnections could get weird because while some amplifiers back then had the familiar auxiliary 12 volt input wire to trigger the amp on, other amp designs had a 12 volt *output* that powered the radio and switched the amp on when it sensed the current draw of the radio. It could get convoluted when hooking up multiple amps and signal processing equipment that used different turn-on schemes or when the radio was digital and needed to drawbpower for its memory function (or had a separate wire for illumination of the dial, which was intended get hooked up to the dimmer switch for the cars' instrumentation panel). There were a couple times where the radio didn't have a switched 12 volt output for a power antenna or to turn on an amp and so I opened up the radio and added a wire from the on-off switch. Ah, those were the days! No standard design practices for mobile audio gear,, and the installer had to be creative. If the equipment used DIN plugs for audio interconnection, typically with a 12 volt turn-on lead inside the same cable, no two manufacturers used the same pinouts, and I became skilled at making DIN to DIN adapters. I remember an installation I did for a customer with an Alpine deck, a Kenwood EQ, an Alpine crossover and two or three Kenwood amplifiers. I had to make a bunch of DIN adapters for that one!

    @@bigdogbrodavepresents6178 , one stereo store I worked for sold German-designed Visonic (Visonik?) speakers and amplifiers; the amps weren't reliable but the speakers were similar to a/d/s 300i plates and 200c mini-boxes, they were inefficient and power-hungry but sounded good. Fujitsu Tenvox made radio-cassette players that were funky-looking, almost industrial, and built like tanks, and had the most hysterically funny installation manuals with gloved hands that had faces on them pointing out the wiring connections and mechanical mountings. I also remember a few Hifonics amplifiers, such as the "Zeus" model. Even Philips (the Holland-based corporation who gave us the original cassette tape design and later collaborated with Sony to develop the compact disc) got into car audio for a little while with 20 watt and 50 watt per channel amps that were purportedly designed by Audiomobile and sounded like it (smooth and warm, probably MosFet). I sold and installed the first generation Boston Acoustics car speakers, abd owned a pair myself ---- and got paid to replace them all, under warranty a year or so later when the cones all crumbled from sunlight exposure (they ALL failed,, but to their credit, BA replaced them all at no charge to the customer, even several years later, out of warranty). Even the famous B&W, Bowers and Wilkins of England, got into car audio with the LM-1 metal-enclosure, Nextel finished, mini speakers that could handle several hundrred watts and included the same APOC overload protection circuit as their most expensive home stereo speakers and recording studio monitors. ( Nextel, a rubbery synthetic felt flocking or velore-like coating, was like "the next big thing" in metal coatings and finishes for a very short while. The biggest problem with it was, it was difficult to dust or clean). Man, this is making me dig deep into whatever is left of my memory banks!
