In the late 90’s, I special ordered a few MTX 12’s in 8 ohm just so I could put them in house speaker boxes in my bedroom. I use them to this day in my garage.

The Thunder series and Blue Thunder series came out shortly after these things if I recall. The Thunder series in particular was extremely popular. They were well built and powerful as well. You tested a Thunder 2300 back in the day. One of my favorite dyno runs.

I'm a MTX fan ! I have two 22 year old MTX 8000 12"S on a MTX RT2400X that I play hard every day . Still sounds amazing.

Very solid results. Would have loved to have this amp back in the day.

MTX has never let me down. They have made solid products since way back

Nearing 30 years old and still performing well, I'd say it's a solid amp. I've had several MTX amps over the years, and they have always worked very well.

7:58 The black spot you see from the thermal camera on the amp board are the aluminum top from the caps that reflect the ambient temperature probably from your roof or wall that are at colder temp. NEVER FORGET that thermal camera will measure more the reflected temperature from a distant surface unless you correct the emisivity to the appropriate value from the material. typically emissivity is set by default at 0.95.

I had one of these amps pushing 2 15in Orion xtr subs years ago!!! Loved that amp

i remember the MTX Terminator Sub's from the late 80's early 90's they was no Joke back then

Back in the day one of my buddies had MTX subs and I thought they were some budget brand, had no idea til later that they made kick azz amps and subs.

Really appreciate both Williston Audio channels, such a wealth of knowledge & history contained in these vids.

I remember the black gold subs did not come with the gold logo on the front of the sub. They gave you a sticker to apply yourself. And it was nearly impossible to put it on perfectly. I had 12 of the fifteens in a Chevy Astro van. Drove me insane that my logos weren’t perfect.

I rocked the road thunder stuff at Sears each time I could, you were expected to! Thanks for the entertainment bro. ✌️

I can vouch for Amp Guru. Fast shipping and his stuff is awesome!

Always been Mitek fan. Using 2 12” 9500’s right now with 1501D

I had 2 12" 4ohm black golds....awesome subs

Nothing like old skool through hole mounted electronics.. I can smell the parts in that gem! Nice work Big D!

The black and gold was 🔥 I always wanted a set of 12” and that amp 🙏

What a solid performer! Every time you bring the Thunder, the headlights WILL dim in your 90s Honda Accord !!

Awesome vid man!!! I absolutely love the mtx black gold line up! The black gold 15 floor speakers are still one of my favorites to date.

Never have seen this amp. Regardless of the results, amazing content as always!

Would like to see output at 12 volts, back in early 90s we did tests for SQ with motor off any amp that had more than a 25amp fuse was considered s monster, boy have times changed

Wow a mtx amp line I haven't ever seen .

Mannn I certainly remember when 500w of MTX power sure would rattle your brains lol-ol-ol unlike today's audio equipment I had a pair of blue thunder or road thunder 15's on a 500w amp and it was known as one of the louder setups on my town back in mid 90's and then Lanzar became prevalent and one friend of mine squeezed 6 15's into a dodge neon and earplugs were necessary I am still amazed how the amount of power has so greatly increased but we definitely were loud back then with very little power and all the extra batteries and alts were never needed just one extra batt near the amp and you were set! I actually still have the subs that I eventually upgraded too which was a pair of Kicker C15's at 750w rms each single 2ohm coils and you throw those in a big sealed mdf box and they would flex your windshield and metal panels like rippling water I've always wanted to throw them in a box and in a trunk to see how they stack up to today's audio equipment and if I still would be impressed by them at all 🤔🤷‍♂️ I've got a whole slew of oldschool A/B and D amps I could run them on that I never would have been able to afford back then...

Gorgeous amp. Thanks for the review!

The best amplifier reviews on KZfaq! Next, you need to review subwoofers, mids and tweeters... Everything car audio. I'm sure JP will take care of you, so both of you can further grow.

In the early 90's, the big 3 was, ( in Richmond, VA) kicker, Rockford, and MTX (price per watt )

I love the Williston Extras Big D

My first subs were 12” MTX Thunder 3000 and First component set with MTX 4” with 1” tweeters the subs were good but the component set was very good. I’ve always liked their products

Nice video, you know whenever it's got MTX in it I'm gonna click 😁

Cool video D thx! Plz run the dd1 during the bass demo especially at 4 ohms. I would have liked to see the rise thx.

As a regulated supply, it doesn't seem to do it in the way we normally see with more modern amplifiers. It almost looks like it takes the primary 12v input, sends it to a first power supply for regulation (I'm guessing between 18-25vac), switches the duty cycle of the first fets in the line to regulate it, sends the unfiltered AC voltage to another transformer for further boosting, which might only be 1.5-2x input from the first transformer. Iirc, Hifonics was the first to use duty cycle trimming to regulate output in their VII (7) series amps.

More MTX amp test please Big D!

Big D. Off topic, but I got a video series idea for ya. How about a “help plan my system” sort of thing? Once a month you suggest best equipment for someone’s goals/budget/vehicle. Or this might be a cool collaboration series for you & HiFi.

Never seen this particular Black Gold MTX in stores, magazines or on the used market. Cool stuff D, I like seeing amps I'm not familiar with. I bought a Thunder 280 used in 2000, it's STILL working, powering a 12" in my homeboy's truck.

Looks like they might actually be dual power supply, I'm no amp expert but from what I've seen power toroid coils are usually multi color windings, where as the choke coils and windings are usually 1 color. But I'm no expert just my opinion and observation another great old school video D!!

I remember these and the thundercast and thunderpros.

Of all the MTX amps I've never seen these. I have the MTX 2300 and a Alpine White 4320 4 channel amps. I've always been my favorite look and believe they were the best power amps they put out, tell the one you and Donald put out stupid crazy power down to 1 ohm mono😮. Now back to my regularly scheduled program. 👍

Wish I had 42 aluma pro sub from 94 95... 😊 Mtx always been decent quality 👌

The "dual power supply" refers to the primary and secondary sections of the power supply used to push each stage of the Darlington circuits. I have an Urban audio works amp that has a similar setup. You're right though it's technically one power supply with two separate outputs to provide two different rail voltages

Back before I knew anything about car audio I knew the name MTX. When I first got the money to get a real system I had two thunder 9500 tens in a sealed box being pushed by 1800 w linear power amplifier. Honestly wasn't that loud but it sounded real damn good. Got hard up for money and had to sell it. I should have done anything to hold on to him because MTX quit making them and replaced them with the 95 series that don't sound near as good.

Great! As usual.... Thanks

Fairly surprised. This thing seems about 10 years ahead of it's time.

im coming to where the old school is!

Wish u can get your hands on the old school tsunami amps and test those!

Be nice if Corsair had some fans that would fit those. The Mag-lift Zero Noise fans have worked great for years in my PC. Either way, Ya gotta love those good ole regulated amps. So much easier to select speakers when you can trust the ratings. Like actually trust them. I could only image how many speakers have been blown because an amp rated at 600 watts, is putting out 900 or 2000 etc.

Love those amps and subs back then especially the subs back in 95 a buddy of mine had 4 of those mtx black gold series subs in a 87 trans am in a sealed box on a hifonics boltar the bass would mess with your vision my how i miss the 80s and 90s

Interesting - when you said fuzzy logic rail control power supply, my thought was it was a class T amp - nope. But seems to have taken a little element of what makes a class T amp work. Don't mind a well executed T-class amp, but have to be aware when it clips, it clips at the rails, and so things fall apart quickly sound quality wise when driven to the max. Wonder if the same might be happening here.

Cheers & thanks! I’ve missed this video when posted, but I really did like that design on that series from MTX. I wanted to ask, have you ever did a review explaining how and why amps are classified? I was under impression from previous information someone said to me when I was buying my Memphis 1100D amp: class A/B amps are cleaner power for sound quality, while class D are more like “raw power” for smaller but more powerful amps. And, since class D were raw power, they were more power hungry also… is any of that true? Like the vids, thanks again & Peace

I had the black gold mtx subs never seen the amps they remind me of my favorite class ab 2 channel alpine 3545 amp nice pick up.

I would replace the fan, with a modern day brushless equivalent; BUT SAVE THE ORIGINAL! lol! Black Gold MTX equipment, are the unsung heroes of old school car stereo! Their equipment was so far ahead of its time. Granted, it took some power to make power, but good Lord, the results! 🤤🤤🤤 And that’s not even beginning the conversation about the subs… 💛

Nice video my friend

Love a Old school

we had rto terminator gx ,4000 to 7000 serie . people told in that time IT use mtx boards .

Great video!!

Very similar style as the Alpine 3545 !

.,,,Love the Guru. I buy from him regularly, he is great seller with a big selection of unusual vintage stuff, my kinda people Big D.The history of MTX is interesting...Someone should write a book about who made what back in the day of American car audio...seems mostly in 3 states: Arizona (MTX.PPI,ORION,RF,PG) CA(Soundstream, Zapco, Phase Linear) and FLA (Mmats, US Amps, Power Amper)...of coarse McIntosh in NY....maybe you should Big D, Im a buyer when it comes out

Great amp, but I'll stick to my 2300's after seeing this video. Still beautiful amp to have if you can find them.

Rad, I have always wanted to see these in action. I think I will stick with my thunders though.

Never had one of the amps but my first subs where MTX roadthunder II 15"s 😁

Big D any chance you can can find some old M&M Godfather Subs? I would love to see those and how they would perform.

I like the sound of fuzzy logic rail control but than clip indicator lol

I miss MTX. I also miss COUSTIC. Big D you should test a COUSTIC amp!?

Hey would love to see an Amp dyno on the new bass rockers amps. Just picked up a z4000.1d. Seems to put out more than my Orion 1500xtr. For the price seems legit

Nomenclature. That’s a new one. Thanks D.

I had a Black Gold 12" that I got clearance in the early 90's (I think). It was a good sub, but absolutely nothing special. Pretty sure it was just one of their Thunder subs from the time, with a pressed paper cone with the black and gold dust cap.

Was looking at mtx black gold back in 95. Ended up getting the Soundstream Continuum instead.

I have a mtx rt-a2110 Amp silver in color with blue yellow & pink MTX letters....question...who made the silver amps? There was a 4x50w,2x30w, 2x60w and the 2x110w like I have

Quality amps

Why are you not testing the mtxd81000d

I had several the later black and gold 275 and 2150 amps loved them could run them much lower ohms then they said I don't know if they was as heavily regulated as these. But yes there beautiful amps

Did The color change on the amp when you was testing it from green to orange to red

Wow, those look very much like ppi boards, if it's not a ppi board then they are very similar. 500 watts on 8 pair of bjts, not real impressive. I bet it uses the sg3525 pwm like ppi uses. A true dual mono amp must use two pwms to be a true dual power supply , not to mention transformers. Beautiful amps none the less. Great vid.

Do a GROUND ZERO AMP TEST LIKE THE IRIDIUM SERIES

Very nice a like sound

Great amp

👍

Still a clip light in 1994 un heard of

Please do the red and black crunch power zone 5000 watt mono amplifier

So wouldn't it be fair to say the amp did not do it's rated power since you had to increase the fuse amperage?

Just as good as an Orion 2150sx

These were hard to get and I worked for a MTX dealer in 1995

😎👍👍

That looks so close to the ppi pc class amp boards.

Things that dreams were made of BITD

MTX had a very strange person running the company. I don't remember what year it is was. He basically said all high powered speakers and amplifiers were pointless to make/sell because you didn't need that much power in a vehicle. That kind of freaked me out as a sales person at the time........every body wanted a Zeus, 4 EV's, a Zap, and a Kenwood at the time......and Horns too ( tweeters ).

Fan sounds like a 1200W Ninja blender.

I still have my MTX power 2160

There is a rapper/KZfaqr named crypt he has a list of music he allows people to use on there KZfaq channels maybe check him out U might find a few bassy song's

You can play the other stuff for 15 seconds or less, Soundman Car Audio channel always plays 80s and 90s music. STOP BEING RIDICULOUS, NO EXCUSES.
