Old School Stereo focuses on displaying and testing mostly pre 2000's car audio equipment. Some old school BMX, computer, video and other retro tech may be shown. I also run Williston Audio Labs another channel which mainly focuses on current car audio equipment. If you like stereo / audio / video / portable gear from the 80's and 90's, you'll enjoy this content.
Belle was always my fav bomber, from games to movies, I've actually paid $500 about 10 years ago at a airshow to go for a ride in the ball turrent. I'm specifically looking at the VIVBelle, thinking about gifting it to my father, a beautiful plane, a beautiful amp!.
"LETS GO FIND ANOTHER AMP!!!" haha... that was/is so me. hahah... I missed the ole days and the old school amps. Thanks Big D, I really appreciate your content you share.
I want to see the old black orion 800 watt against somethin I had one rebuilt 2 times the first didn't go to well but I loved that amp it got stolen from me I want to know what it would do I pushed a solo Barack L7 12 with it it beat that thing like a war drum
JC Whitney! 😂😂😂 I remember those catalogs. Unfortunately for me, I was in a bad car accident (broken neck, back, and left femur) in 1993. Fortunately, I fully recovered and that accident got me $70k from the insurance company. I was 18. I bought an ‘89 Chevy Blazer and spend nearly $3k on a full install of Alpine (head unit and mids/highs) and 2 Punch 15’s on a Punch 200. Had one of the beefiest systems in my town and was a rock star for the next 2 years. 😂
Is it me, I kinda prefer the old school era of car audio amps were it was only like a dozen flagship brands, that were hard to obtain. now days the market is oversaturated with hundreds of amp brands. some one can pull up on you, blow you out the water with a full bridge, brazilian amp system. that was a tenth, the price of a high end vintage system.
I like Phoenix Gold, but after owning a few RF amps the prime series is pure utter shit, the Punch 60 was another story it was a beast, so RF as long as it aint prime!~ Hooked up a Punch 60 in Tri-Mode to a pair of MTX 10in in separate boxes with a Orion 15in on the bridged channel for a old friend back in the 90s.

15:55 seem like the triple Darlington design was just a very small window in the car audio history. I would consider those Phoenix Gold amps during that era probably the best sounding amplifiers I've ever used especially when pushing them right to their limit.
I concur, USA made, triple darlington was an incredible era. P.G. offered triple Darlington on their flag ship amps all the way to the Xenon series. New units are still in stock & being sold at this time of this post.
This is a far better test than the dyno test prior... hands down, the PG is a better amp. Yeah, the RF did more power but highly doubt you would notice the difference.. but I believe that PG amp is more cleaner distortion
That’s a toss up. As an RF enthusiast my heart says RF. That said having actually seen and heard both of these in action my hands would be reaching for the PG. They really were ahead of their time. Great video, thanks for the trip back in time.
Been a Rockford fan forever, so I would go with them still. Over the years, owned zero Phoenix Gold's, one Orion, 1 RF Power 1000, 3 Power 650, 4 Power 300 and one Punch 150HD. I think I like Rockford!
Big D dug this video out of the old school vault!! Still a good video! You have really polished your delivery over the years, but the basis of the channel has stayed the same and that is what a lot of us love! You show us what these amps actually put out vs what they were/are rated at. Thanks Big D!!!
As much as I was involved in car stereo for nearly all of the 90s I rarely ever saw Phoenix Gold yet it was one of my favorites for my ever running wish list.
I remember pulling several Rockford Fosgate amps and swapping in Phoenix Gold amps. I did what the owners wanted pretty much, no complaints BUT, as them amps go, RF kinda had an edge in sound thanks to KNOBS. BUT.... To be honest them customers kinda wanted NO KNOBS. They were searching for the illusive SOUND QUALITY in an Automotive environment. Only so much SQ in a CAR I say. Seemed at the time to be a DOWNGRADE but I got paid. I remember PG being one of them companies that really took market share from the other established brands at a TIME. Customers were looking for something more... EVERYTHING was GOLD PLATED.... MOBILE Gold Plating companies... LOL... I REMEMBER... BDBD/2024
Please dyno and sq test, Butler Audio Tube Driver Blue vacuum amplifiers, wish someone can send BigDWiz a TBD amp so he can test it, would love to see it tested, please make it happen, thanks.
In 1991? I'd have to go with the PG MS275. Just because that's the one I wanted back then but there were no PG dealers around me. It was a totally different time back then. You really had to run whatever your local shops sold. Especially if you wanted a warranty. Nowadays it's just click- Buy It Now. This newer generation will never understand the struggle!
For some reason I wasn't a big fan of Fosgate amps back in the day, I was into PPI and Soundstream but I always loved the heatsink design of the Punch 150. I had a friend that had a Punch 150 powering two Fosgate 15's and two Fosgate 10's and it hammered!! Another great video!!
This has to be one of Derek’s old videos that he recorded several years ago and just never put up here on RU-vid. The cadence of his voice, the tone of his voice, the choice in words, and the test procedures all point to this being an old video.
Hey Mr Williston, great to see you keep dropping content and keep our eyes and ears open for more of your amazing work. I have asked many questions and put plenty of feedback on your videos, this is yet another backseat driver opinion again (smh lol). You should do a “Derek’s Degree” segment and explain more into some of the complexities of the things you do. I wanted to know the physics or reason for loading down channels on amps when testing. Why do you need to? To relate what happens if you don’t load them up. Also, when you test multi-channel amps, your fluke readings (5channel amp reference) are unavailable. Lastly- because of those gigantic amp draw readings, how can a person put an amp rated over 800watts into a car w/o having a 300+ amp alternator? But, keep up all your amazing and awesome work- you always seem to keep a plethora of old school information- I would be interested to know if you can locate any from 7/12/98 USAC competition in Milwaukee? I took 2nd place & would love to go back and see the results or even some photos again. Cheers
@@JasonWW2000 this is combination of both…I think there is a lot of information that goes over my head, and I can only assume there may be many other who sit in the same shoes, but just don’t take time to ask. I think it’s up to people like us, me & you @JasonWW2000, who put ourselves out there to ask questions without fear of feeling threatened or foolish. Cheers mate!
@@r3d-1truth17 About loading channels: A car amplifier has a power supply section and an output section. You want to put a load on each output section channel so that the power supply side is also loaded down. For instance, if you have 4 channels but only load down and test two of them, there's plenty of reserve power in the power supply section so the two tested channels may read higher than they should. Unscrupulous companies may use this technique to boost their power ratings. Loading all channels puts the power supply section under full load so you get a more real world power rating.
@@r3d-1truth17 About the power draw of the amplifiers from the vehicle: There are several factors your not considering. First, the battery is the main energy storage device. Typically an amplifier will draw instant power from it and then the alternator will kick in a second later and start refilling the battery. Second, the amp dyno is receiving a full volume test tone. That's very different to music. With music, the volume varies and the bass (which uses the highest amount of power) surges. It's usually a quick burst of bass energy with gaps in-between. The bass amp draws power in bursts while the alternator is recharging the battery at a steady rate. Third, the frequency of bass also plays a role. Lets say you have a 1 ohm sub in a ported box tuned to 30hz. Bass notes around 27-33hz are going to see an impedance around 1.3 to 3 ohms (the lowest ohms). So these frequencies draw a lot of power from the amp. A bass note of 45hz might be around 15 to 20 ohms and draw very little power from the amp. You can put a DC clamp meter on your amp an see the draw change with frequency. So the song your playing can have a big effect. So all this combined means your not drawing as much power as you think you are. Maybe 1/4 to 1/3 of what you thought when cranked full blast. This is why most folks say a stock electrical system (80A-100A alternator) can handle a 1,500 watt amp.
