OLD School Amp Dyno
Вставка
- Опубліковано 6 лип 2024
- In this video we test out and dyno this old school Alpine MRP-M500 amp, this version was replaced by the very similar MRV-M500 and both should perform about the same. In addition to testing with load resistors I also test with a subwoofer to show you real world performance.

About the amp dyno: I am using resistors along with an SMD DD-1 plus and and SMD AMM-1 to detect distortion, measure clipping, and measure power in watts. Unlike most amp dyno videos I also include a reactive test to show real-world amplifier power. @meade916 @wal

I have one of those old alpines, and I’ve had it since about 2010, and I’m STILL using it. It’s been through about 6 different cars.
This one is in my teenager's car at the moment. It's a rock solid amp and it's a great value.
I have the m1000 version. Had it since new. Beat the crap out of it with different cars, subs, low impedance, low voltage, etc. It just won't die. Currently powering a resilient sounds gold 15. (Or trying to) 😂
@@anthonywelliver9050 It's a damn fire amp.
Same with me bro I have the MRP m2000 it’s out survived many cars and speakers lol
I still use V12 T500 starting to wonder how many cars it will pun in grave 🤣🤣🤣 did't got any repair or something and still work perfect. Good old school tech
i bought this amp in 2009 for a jl audio 10" and pumped it every day, now i have it pumping a sundown audio 12" and its still doing just as fine as the day i got it home, great amp
It is a solid little amp!
Great video! There are a lot of factors that effect impedance with speakers, so that's why the resistive loads really tell how the amp performs compared to other amps. It's awesome to show the actual power going to the speakers as well because it's rarely anywhere near what people expect it is at a single frequency. Music playback will vary the impedance also and "music power" may be much higher, but it's usually for short periods. Keep up the great work, I love to see more amp tests because there are 1000's of amps out there and the more people testing, the better!
Thanks man I appreciate it! If my audience enjoys the video I'll film a few more, I love to build up my test bench so I could try out some more powerful amps.
Have had this amp for years it’s amazing very impressive we’ll worth the money
I have gotten a lot of great bass out of mine.
I love that you hook the amp up to an actually speaker
Yep, I'm trying to do something different. Hopefully after I do several of these videos I'll have enough data where I can do some analysis, and get an idea of how a traditional amp dyno can predict real-world power.
It's been a long, busy day. Glad I caught this before I crashed. Glad you are putting those SMD products to work for ya.
Thanks for dropping by.
I have had several of these over the years and they never disappoint
Rock solid amp.
Great dyno man loved the video , also had mine wired at 1 ohm for years no problem and great comparison showing the load differences
I'm not surprised to hear that it can handle one ohm. I was under the impression that there was an even newer one out that was designed to run 1 ohm.
These are how amp dyno vids should be, interesting and to the point.
Thanks!
I had that same amp and the model before it around 2006, had it hooked up to 1 12 and it was really loud, 1 of my fav amps for price I've ever had, was only about 18 so it was impressive
That's awesome results for this amp. I used to have that amp and I gave it to my uncle for his truck build and unfortunately he sold the amp for who knows what reason, I was so sad that he did that. I would have kept the amp if I would have known his intentions were to sell the thing. SMH. Thank you so much for making this video man. Keep them coming.
That's how it goes! I regret every piece of audio gear that I've ever sold or given away.
wtf who does that?! 🤦🏽♂️ my dad just gave me his and his old 2 12” alpine subs these are staying in the fam until they break 😂
@@RJ-mh3ox I know!!! That was sad, man. I won't do that again lol!
had one of these on 2 10's and it hit pretty hard
Perfect amp for a pair of tens.
SICKKK ! Love these amps and they are everywhere cheap used and super reliable
It's nice to see manufacturers that actually design their own circuits, they are usually rock solid unless they are abused and will last for years. Now that's not good for the independent repairs guys, they don't see allot of them and trying to fix them can be a pain.
I guess there are pros and cons to everything.
Thanks Justin. Looking forward to Boss amp dyno and hopefully many others.👍👍
Heck yeah!
Just got an MRV500 on clearance- brand new and can’t wait to hook it up…. Hopefully today!
Very interesting. Car Audio been hobby 4 decades. Can't get enough info, that is backed up by results/data. 👍
More data is always better!
I bought my mrx110 over the 240 & i still don't regret it the older i get & realise about electrical power & box size is what really matters until you want to go competition
Great video . So informative
Glad it was helpful!
How did you power this amp? I hate the power connectors on it LOL but I love the amp
2006-2007. The amp was replaced by the MRP-M500 in 2008, maybe 2009. I have the 450. I've had it since 2007, 2008. It's still going strong, every day! Great amp.
I'm running a Kicker CompVT 12, 2 ohm.
I have the mp450 and the mp650. Very good amps.
I've been pushing one 10 with my old Alpine MRX M100 since it was new. I've considered upgrading to a newer amp but after watching this my old Alpine isn't going anywhere.
I have had this amp since 2008. Never have any problems. Still cranking to this day.
Good job💯
I used one of these to power three Rockford Fosgate P1 12" subs in a 4th order bandpass box. The results were pretty surprising.
I imagine so!
Everyone knows every Rockford sub comes pre-blown from the factory. You could have powered those speakers with the headphone jack on a cell phone. Get a quality sub next time.
I love alpine amps. I have the mrx-m110 hooked up right now to the termlab with a 4ohm dummy load. Def doing rated and then some.
It is a solid amplifier.
I have 6 of them installed in my truck. I have an ‘04 F-150 8200 GVW. Alpine stereo, 10,000 watts, 13 Alpine amplifiers, 16 vocal speakers, 6 10” Skar Audio SDR subwoofers in a custom enclosure, dual alternators, so much more. Check my channel and on TikTok.
Great and detailed review.
😎👍👍
Thanks!
I've got two MRV-M500 that I'm trying to install currently. Not really motivated to go into the garage when it's -10c (14f) outside. Would have loved to see if the newer model did better than it's predecessor.
They are great amps!
Nice video, i personally run only alpine amps, they never disappoint. especially pdx amps that push same power to 2 or 4 ohm loads.
Thanks! Those are great amps.
Any info on Alpine MRD-M1000 will be greatly appreciated..
I think I've had more of these amps then any other. Can be had for $50-60 around me and puts out great power for money. Box rise is a killer!
I never can seem to find a decent deal on used amplifiers, they're either beat to hell or the seller is asking darn near full retail for them.
@@DIYAudioGuy I live 45minutes from Seattle and the deals on plentiful on everything. I think it really depends on where you live and how big the population is.
Alpine def makes nice equipment. I've got a couple type r's in the closet. They sound great
Yes they do
I have been using alpine mrd 500, pdx f6 and pxa-h701 all the time still amazinggggggg performance, my ears doesn't heard something off
It is just without dsp my sub cracked 😅
👍
I have the alpine mrv m1200. I've has a handful of amps and this alpine amp has crazy power. I have a skv2 2500 skar and the alpine sounds and his harder. Any possible way if you happen to get ahold of 1 id love to see what it pushes. Thanks
My guess is that it probably pushes out more power than my current power supply can provide.
I have been running the mrv500 at 1 ohm for a very long time. This amp holds up.
👍
yeah alpine always made good stuff.
A solid, reliable brand.
It looks like you're an Alpine guy. Do you have any thoughts on the Alpine s-a32f 4-channel amplifier vs the Alpine MRV-F300? They're both 4 channel and about the same rated output. Is one just an updated model of the other?
Alpine makes good stuff, but I don't consider myself an Alpine guy. I don't have any experience with that particular gear so I can't tell you anything more than what the spec sheet says. The good news is that Alpine specifications are accurate.
Very cool video. Looks like a really good amp. I'd be interested what kind of peaks it would give with real music. I'm guessing easy over 700 watts when It hits a quick hard bass note and the caps recharge. If you want to learn more about electronics, 2 books I recommend are practical electronics for inventors and electronics for dummies. They will tell you how to read a schematic and how the components work and how to test them.
I might have to give those a look.
Had a MRX-M55 pushing a SA-8 v2 almost 10 years ago, birthsheet said it did 581w @ 2 ohm
Sweet!
I have this amp... interesting.
Glad to help!
I have this amp, this amp is amazing g
👍
These Alpine amps fall into a category I call "common man workhorse amps". Not a lot of bells and whistles as indicated by the lug style connectors. These Alpines arein that category along with JBL, Infinity, Sony, Clarion and Pioneer, etc. from the same era.
All very solid performers that usually make more than rated power and are durable. They are often overlooked nowadays and as a result they can be had for cheap.
Nice review and demo Justin. Good info. 👍
Absolutely, they are great amplifiers.
how to connect remote to mrp f450
I tuned in for the T Rex and stayed for the content.
😂
I've had a V-power mrp1000 mono block (same amp,just bigger) for over 10 years with a no sound fault. Comes on , no smell, no sound..I wish I worked. I've kept it this long hoping I could fix it someday
I still used mine in 2024, mine is 550w and never let me down
Mine is in one of my kid's cars.
I have a m450 that I got on clearance at Best Buy for $50 when this one came out. I ran it for probably 7 or 8 years with no problems
That is one hell of a deal!
I currently run one those 450's going to 2 fosgate p1 10's in a sealed box and it POUNDS.
Can you dyno a precision power i640.5
I havnt seen nobody dyno
I would like to! Do you think you can get precision power to send me one?
For all the "Brazilian" guys out there...here is a full bridge design. Alpine, JL Audio, Rockford and others, have used ful bridge for years. Great video, thanks!
Here is an example of a full bridge amp from Alpine:. ua-cam.com/video/QggLZb77_sU/v-deo.html
@@DIYAudioGuy correct, I was stating that this amplifier was full bridge...the Alpine tested. People say, full bridge isn't reliable. Companies have been utilizing this tech, for years, as full bridge has been around forever.
I owned two of these amps and ran one Alpine Type R 12 each @ 2ohm. Grab these if you can find them!
They are rock solid.
Did you dual amp the R12? Both amps feeding one driver?
Do you think this amp can power 2 Pioneer iB Flat 12 inch subs
I don't see any reason why not.
I regret ever selling mine. Jl500.1 are comfortably underrated as well.
I still got my mrp-m500 since 2009 gone through others but they all died on me
I just installed this one back into a car.
I have 2 of these sitting in my garage. One mrp-m450 and a mrp-m850. You think they're are worth anything?
The market for used gear can really be hit or miss I'm sure they're worth something to somebody.
@@DIYAudioGuy I guess I have nothing to lose. I'll just have to look at what these new amps are going for and try to post it at a reasonable price. I have a Boston acoustic G5 also sitting around from that era as well.
im a bit confused how do you run it in 2 ohm does the amp automatically knows when you hook up your sub??
There are no sensors or anything like that if that is what you mean. The amp will just produce more power when it is hooked up to a load with less resistance.
@@DIYAudioGuy so no switches to flip. Thank you sir
it's pretty decent underrated , but the beasts are orion hcca 3k that output 10k+ rms at 0.5 ohm , russian amps that do the same , some brazilian amps like powerus or bully performance
That's some serious power.
@@DIYAudioGuy Yeah , but i gotta respect alpine too , they make lovely headunits to be honest
When you try to explain that just because you have a 3k amp you're not getting 3k .they look at you like your crazy. Good explanation
It's complicated stuff.
At this point 2008 is fast approaching Old School territory
It was a long time ago
Is this how people wire 1ohm amps at .5 ohm. Because of box rise?
Yes, but you have to be VERY careful. It's only recommended if you're an SPL competitor. Competitors regularly push their gear to the extreme limits knowing full well that they're going to break something and start fires. For your daily driver you need to error on the side of safety and reliability.
This amp does 1 ohm just fine was almost as loud on my vxf 12 as my memphis prx1500.1
I am not surprised to hear that.
Selamlar kanalını Türkiye den takip ediyorum ve özellikle eski okul anfileri seviyorum benim basit sistemimde jbl 1200.1 ve 75.6 var iyi çalışmalar
Good looking transformers inside the amp. Kinda surprised at the lower voltage Caps though. Generally higher voltage is better, say 50 volts instead of 25 in terms of performance and sound quality. But overall, a pretty good and clean amp design. Certainly, worthy of the Alpine name. Especially with its capable output in watts.
It's a fairly old amplifier at this point. I imagine the newer ones are even better.
Is it a good amp???
Watch the video and judge for yourself.
Well I see serious power . The copper and diodes amounts
👍
Man I have one of those sitting in my room
It's a great amp! Hook it up and drop some bass.
I have the same amp. Quality that lasts.
Mine has been kicking around for almost a decade at this point.
That's watts up
Don't feel bad if you can't figure out the configuration of that Alpine. Barevids will tell you how complicated they are but it all is down to quality Alpine designs their own amplifiers.
I don't feel bad, I can't know everything.
Had to pull mine out the closet to replace a garbage taramp
Alpine was quite high end before 90s but went china
The old saying was "Them be Alpine watts"
👍
The inside's of my amp are different
Might be a newer model.
The smd amm-1 has very cheap leads and female banana receptical. If you break it don't expect a response from s.m.d. I know
That is not fun.
Barevids. For internal of amplifiers.
He has mad skills.
The term "box rise" is a misnomer and should never be used.
It's right up there with subsonic filter.
Sucks
Check out barevids, he’s an expert on amps. Most amps are built the same, the big name brands just like to rip you off
Absolutely, Sam knows his stuff.
On the contrary, companies like Alpine, JL, Kenwood, Rockford Fosgate design and engineer their own bespoke circuits, some are even using full bridge topology for their designs, the ripoffs are the cookie cutter Korean half bridge clones all over the place, some are so generic that it's hard to tell the guts apart.
