1995 Rockford Fosgate Power 250m2 Amp Dyno Test and Review

[@one7decimal2eight]

That paper the amp is wrapped in hits me right in the nostalgia when I bought my punch 100ix for over 400 bucks! Took me many hours working for 4.25 and then 5.50 an hour to get that bad boy! Loved it. Sold it in the late 90s.

[@wal]

Yeah man it was so cool they did that

[@Carl_Jr]

Me too! I bought an original Punch 100 DSM (no "ix") brand new in 1993 and I still have it. It finally gave out about 12 yrs ago but I refuse to part with it. 😂

[@Adam-nv9zo]

I know exactly what you mean. Love those old Rockfords.

[@matthewstorm5188]

@Carl_Jr Consider getting it repaired. These old amps are becoming quite valuable these days, and are definitely worth repairing.

[@nutxo]

HEH, Car toys had an even and a sale. Rockford was there and had reburb 200ix for 200 bucks,.full warranty. I bought 2. One had broken feet so I sent it back and a week later I had a new one. I went to install and the second amp had the threads stripped out so I sent that bacvk and they sent me another new one. 2 weeks later I got a call that my new amp came in,. I was like "Okay" then a few weeks later I got another call that my new amp was in come get it....I traded them for a 78 malibu..

[@slimjim1104]

I had many fosgate punch series in the 90s and early 00s. Great stuff. Eclipse was another brand I loved. Had a massive 5 channel that just plain kicked ass. Never went back to multiple amps after that.

Being from new Orleans. Rockford fosgate and alpine pretty much ruled the land. I wish I would have kept all the Rockford amps I had from that era. I do still have a punch 250.2 Darth Vader series lol on (6) 6.5 skar evl subs at 2.66 mono. Still rocking it

[@vettepilot427]

I would love to see a review of the Power 50x2. This was the "cheater" tombstone amp from this time period and intended to compete with the Orion 225. The paint on these was more of a silver/gray and supposedly had ceramic added for better heat dissipation. I had 5 of the Power 50x2's in an Astro van on 12 Punch 15's with another 4 Power 50x2's running a pair of MB Quart 1" tweeters, 2 X 6.5" Quart mids, and 2 X 8" Quart mid basses in each front door. I was ROCKIN' in 1997!!

Big D Whiz,It’s funny 😎You mentioned that this amplifier looks like a George Foreman Grill 😱 Because I knew the founder of Phoenix Gold Keith Peterson .I also knew the designer of The Cyclone .The only Servo Woofer .Plus he designed the Titanium Series and the Tantrum series speakers .It was a very aggressive line of speakers .His name is Dominic Bonocontri . I was good friends with him Plus Jerry Demaze who was the head of installation and technical support and custom fabrications Anyways when we saw the New Rockford Fosgate Amplifiers .We all agreed they looked like a George Foreman Grill So we were going get a Rockford Fosgate heat sink and make it into a George Foreman style grill .Then say we are “.We are Cookin with Fosgate lol Now you will probably think how will he do it ? Or could he do it ? Remember the Show Get Smart ? With Secret Agent Maxwell Smart? He had a phone in his shoe ? Well I made a functional Shoe Phone Also I mentioned 2 people at Phoenix Gold who were expert designers ,engineers and fabricators So the possibilities were unlimited Plus Phoenix Gold Hand built all there heat sinks and everything in house From start to finish They also made Crown and Carver Professional. Derek I enjoy your content.Your a honest and straight forward guy .Who loves old school car audio Who could blame you . The Old school audio had much more character ,more interesting and innovative They were hand making speakers and amplifier.Right here in the United States I actually watched my Phoenix Gold amplifiers being built Plus they modified them for me 😇

Back in early 90s a buddy had a hatchback with MTX 12" x 2 box and 2 Rockford Punch 45s. He originally had 1 45, and it was pretty loud. There were never any measurements. Then he got another 45 and ran each 12 on each amp bridged. It definitely made a difference with the 2nd amp, but it absolutely was loud. I remember after one night finding blood on a q-tip cleaning out my ears. I don't know 100% it was from cruising around in his car but damn, it was loud and sounded good!

[@logiticalresponse9574]

man them punch 45's were on the other side of the state as well in lake charles pushin all kinds of subs from 8's to 18's . there was a mini truck club that was so specific , u needed an s-10 lowered , aftermarket wheels an alpine deck (no lie ) and subs . almost all of'em had Rockford Fosgate or JL sumptin in'em . called them selves sweet & low and even used the logo , modified slightly .

Awesome little amp. Should have hooked up that little led visual indicator bar they have too. Keep em coming man.

The dynamic burst may be affected by the caps showing their age and not performing like they normally would. Even Nichicon caps don't last forever.

[@BenDeSwert666]

Yea, I was thinking exactly the same thing.. These caps are almost 25 years old, they lost the capacity to give that extra little oomph to be the dynamic power house it probably once used to be.

Back in '97/98 year I was doing DB drag racing. I had two of the Rockford Fosgate 250M2 one to each Rockford Fosgate Power DVC15s 4-Ohms. running one to each amp at 2-Ohms so the amp was seeing 1- ohm per Sub. With a standard ported enclosure tuned at 35 Hertz it did 154 DB using 35 Hz Tone Burst off the DB Jams Vol.2 CD. Always had to have an extra set of subs during competition. Rockford Fosgate's power DVCs of the time just would not hold up, I would melt the voice coil into the magnet. Rockford's Grand rapid facility was not ever happy when I sent the woofers in for warranty.

[@mattb9664]

I still remember going to the local mom and pop stereo store as a teenager without any money and the sales lady (owner) pushing a hard sale of one Rockford amps on me. A lot of people don't realize that the specified power rating at the < 0.1% THD is why the power ratings were so low on these mid-late 90s amps. When the amp would be pushed under normal circumstances up to right under clipping, that's where these amps would end up sounding way more powerful than rated. The reputable manufactures had the extra power headway built in by just stating the power at 0.1 % THD instead of < 1.0% THD.

[@KMFDM781]

I had a little Punch 40 on a set of Fosgate Punch Series 1 12's back in the day....probably 1997 or so. Had it on 2 ohm mono and it bumped pretty hard for what it was, but it would occasionally overload and cut power. Still way better than the LA Sound amp I got on employee discount from Best Buy, lmao. Ended up returning it and running the Punch again.

[@wal]

Man those early-mid 90’s RF amps still killer amps!

[@iamjackalope]

I have one of those in my storage unit. Pulled it out of my Ford Exploder when I got rid of it last year. It happily resided there for the better part of two decades powering the front doors mid/tweets. I'll probably put it up for sale here before to long. It even has the end caps. I have a few old school amps that will likely end up on E-bay sooner then later. Like an ORION XTRPRO 2400 in great condition pulled from the same Exploder. Pretty rare amp as it was only in production for one year I believe. Bumped hard. I have been a big ORION fan for years. I'm building a system for my Tundra right now and it will be my first system that I am not using ORION amps. Thought I'd give Down4Sound a try.

My current go-to home setup is a Hafler Trans-Nova (same basic circuit design as the Rockford Fosgate Punch amps) pro amp driving a pair of first generation B&W 802s. I've recently found a match for my first Trans-Nova, the plan is to rehab both of them and run them in bridged mono. They're among the best-sounding, and most budget-friendly for their quality, solid-state amps I've found.

Hey Big D. Regarding the X-Cards, I worked at a Rockford shop back in the day and they sent me to an RTTI training seminar and they said you could replace the resistors in the X-Cards ( or buy a blank one and put resistors in it) and depending on the resistor values, you would turn that crossover into a subsonic filter at a given frequency for an added 3,6 or 12db bump. Did you know anything about that? I never knew of anyone that did it but was curious to try it.

[@audiokeller1975]

Nice Video👍👍👍 You also have the original box. On the bottom you should see the powercube dynamic ratings printed down to 1 ohm per channel. Would be interesting to know what is printed there. The powercube simulates inductance and capacitance to simulate a speaker which is not a fixed load like our dyno-run-power resistors. These powercube tests were made with 1kHz bursts. This will result in higher numbers. I dynoed a lot of 25- 30year old fosgates. i never had a problem with aged caps. replace them when they start to get bumpy. would be very nice if you can take the time to post the powercube wattage 👍👍👍

I think Rockford started having bigger dynamic numbers when they went to using class D designs. I also imagine a refresh of the caps and components in this 250m2 might help the dynamic numbers. At almost 30 years old now, those internals could use a refresh.

[@audiokeller1975]

no. the 200ix is a dynamic monster. the dyno here is made with 40hz which gives lower numbers. do it again with 1kHz and lets see again. the dynamic power makes the amp more musical.

[@matthewstorm5188]

One thing I’ve noticed about these amps is that the smaller amps seem to be more underrated than the larger ones. For instance, a Punch 60 will put out more than double the 30Wx2 that it is rated at into 4Ω. The Punch 40 is similarly underrated. And the Punch 100 is still very underrated, but not quite as much as the 40 and 60. On the other hand, the Punch 200 is not NEARLY as underrated as the others. Yes, it puts out more than its rated power. But it’s certainly not TWICE as powerful as a Punch 100 or five times as powerful as a Punch 40 by a long shot! The same is true with the 250m2 (and the 250x2, which I have). They’re not bad amps by any stretch of the imagination. But they lack that ‘WOW’ factor in terms of greatly exceeding rated power that you see in the Punch 40, 60, 100, or even the Power 50x2.

[@jameslucas3161]

These silly crossover modules from Kicker and Rockford back in the day were a big turn-off for me on my very limited budget. Alpine had 80hz LP/HP selectable crossover on their later 35XX amps in the very early '90s and fully adjustable crossovers in their first-gen V12 amps in '95, which is why I went with an Alpine MRV-F400 for my first amp. I still have it today! 😀👍

The variables were never precise and to further disappointment users had to rely on the silkscreened graphics to tell them where the crossover point might be. X-cards were exact and also infinitely adjustable in the hands of anyone that took the time to learn how to use them. Also, with minimal added cost for parts to do so. 12 or even 24db slopes were possible in some instances. Subsonic filters, LP or HP and even bandpass applications.

When I was first getting into higher end car audio, I had a good friend that I helped do installs. He had a 12" green IMQ Infinty sub sitting around that he sold to me for next to nothing because he couldn't get it to sound right. I downloaded the manual (way back in the early days of such things being online) and started reading through the manual and the specs - he'd been trying to run it in a huge ported box, when Infinity recommended a sealed box that was so small that the sub would barely fit in it. I ran off to my dad's wood shop with some MDF, whipped out a test box in the recommended volume, and it sounded amazing. I still have that sub. :D

Reworked 100% !

[@MAD450r2]

Does anyone u know still run pioneer EQ6500 in there vehicles. I installed one last week in my friends car he cant believe how much better his sub sounds when amp is in full range.

[@kskate91]

I think the 500.2 might be dual mono? It’s a class AB as well has dual transformers

[@wal]

Turns out this amp, the 250m2 is in fact dual mono. Has multiple windings on the core.

[@I6VALVEFREAK]

have you ever tested a 400A4 and and 500A2?

[@Bassotronics]

Milli Vanilli could not help bring the dynamic power of the lip synch here!

[@wal]

🤣👍

[@Nanobits]

For being an old amp, it does really good, even back then for the shitty speakers of the time it still did very well.

[@SamCogley]

There were some damned good speakers available in those days, even by today's standards - the IMQ Infinty Kappas (especially if you sprung for the Emit-N tweeters - I've been looking for a single for years to replace one of mine that unfortunately had an accident), the old "Superman" logo Oz Audio stuff, anything from Eclipse, etc.

[@Mr_BUSINESS_24_7]

if it's rated 450 and doing 600 or better... .... that's still disappointing ? I thought that's considered an under rated amp ? which Fosgate amp has the yeeee boi dynamic headroom ? good to know Shawn is the go to for Fosgate. I see his name in the thank you list from videos a decade old I have a power 750s that needs some help.

[@vincentchua917]

can test lightning audio s2.400.2?

[@BlueCollarBachelor]

I miss these amps.

[@303nitzubishi4]

I disagree on your dual mono perspective. Yes there is one transformer core but the manufacturer can wind it however they want. It's clearly two completely separate primary and secondary windings sharing a common core. I'd call that a true dual power supply, assuming the core is robust enough to handle the flux from both magnetic fields simultaneously without saturating. Since this is an RF product I'd guess they did build that toroid beefy enough to handle both sets of windings without interference between the two. Awesome amp and insane power output considering it's physical size it isn't huge

8:12 Oh how nice. It's always nice to notice what kind of lifestyle people had. *The difference between an O and a Zero can make a Dead Man or a Hero* The first thing a person must stop saying immediately as soon as he is in military service. The Instructors make you repeat 100 times on the Radio until he asks you if you've ever been in math class.

[@wal]

Good for you!

[@Tron1731]

I'm surprised you found a working example of that amp I had 2 of them and they both popped at 4 ohm , my next amp was a philips sound labs it absolutely slammed I wish I never sold it .

[@Tron1731]

It was a a2150 pcb was gold and I had it on 2 10 inch Kicker solo subs in a 1983 z28 they where in a long sealed truck box face down in the kick it hit so hard people would reach over turn it down cause it caused ear pain

[@wal]

Oh snap?

[@HighBass601]

I had both of these amplifier...still have 500 somewhere

[@TheKeymaster316]

All I know is the Punch 60 that I bought around 92 motivated the 2 Rockford Audiophile 12’s in the trunk of my Mustang very well. Years later the amp failed and I was able to send it back in for a one-time free repair. Blew it again years later but wished I would have kept it as I probably could have repaired it myself. Killer series of amps though and much better than the junk they released 10 or 15 years later at Best Buy. Those were garbage.

[@wal]

Yeah man when I saw those Best Buy amps I was like what happened to RF? Using max power and all 🤦‍♂️

[@Carl_Jr]

You got me thinking about parting with the end caps of the amps I have. eBay, here I come! 🤣
