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.
I'm still rocking my first ever car audio combo. MTX TH800D paired with a 7515/44 at 2ohm. Still sounds awsome. It survived a writeoff crash (not my fault, idiot ran a red light) and is now in the 3rd car it's been in... still thumping away every day. Have that combo nearly 20 years now. Can't fault MTX quality :)
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.
Used to have two 12” 8000’s on and MTX 81000D… and I smoked them. I was SO sad! Always loved the way they performed. Ended up getting that “Sledgehammer” triple 10 box.. it’s was ok… but NOTHING like those 8000’s. Plus I had to seal off that factory port, because it sounded TERRIBLE in my opinion. 🤦🏻♂️🤦🏻♂️🤷🏻♂️😂
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 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 never knew that! That’s crazy! I could’ve done it back in the day, but probably not so much nowadays. Lol! I was the guy that was responsible for putting on ALL of our car club member’s stickers. GOOD LORD did I lay some vinyl! 😂😂 The worst part was, it was a multilayered sticker… that I had to layer. BUT, like you, if they were even a hair crooked, my OCD would kick in, and DRIVE ME NUTS! But I could never say anything, because I didn’t want them to have to buy another $50-75 sticker. 🤦🏻♂️🤷🏻♂️😂
@@Van1018s I used to jokingly say I had it… turns out I really do. It’s semi-mild, but dude… it truly is a curse. I’ve lost count of how many times I’ve driven away from my house, KNOWING I locked the doors, BUT I didn’t double check them.. The next thing you know, I’m driving home, for basically no reason. Now that I’ve come to realize it, it’s a little easier to control. It does come in handy being an installer/builder in car audio though. Lol
The best amplifier reviews on RU-vid! 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.
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...
SAME HERE I'M A DJ AND 800 AND 1200 WATT AMPLIFIERS WERE NORMAL . 2400 WATTS AMPLIFIERS WAS SUPER BIG POWER U DIDN'T NEED ANYTHING MORE SPEAKERS WERE 250 ARE 400 RMS 600 RMS SPEAK WAS SOMETHING VERY SPECIAL WE SHAKE EVERY WHERE FAIRS FETES STREET JAMS THAT POWER NEVER DISAPPOINTED TODAY GUYS HAVE 10 K 14 K 20K NO QUALITY SOUND .LOUD AND OVER PROCESSING HAS TAKEN OVER ?
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
It was enough for an SQ system, pretty much all I was ever interested in anyway....I never had much interest in damaging my hearing, but I did appreciate the installations and ingenuity of the DB systems.I think you can have a fine SQ system with 1 pair of quality components with no more than 100 watts, and a quality Sub with 500 watts...and a quality source...most important, proper design and install....You are right, Charlie, times have changed
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
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!!
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.
I always search MarketPlace for MTX… just waiting for the day that some angry wife sells her husband’s “old car stuff”… because she’s tired of looking at it! 😂😂😂
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.
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.
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. 👍
@@wal2 Yea the shop I worked at got these amps in as well as the black gold subs and thunder series amps. The BG subs were better subs than the BG Amps were amps, especially compared to the thunder 2300 but they were very slick designs and rare like you said. The 2300 on BG 12's was the combo!
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
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
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… 💛
.,,,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
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
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.
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.
I'm still rocking my Thunder 2300 which I've had since new. Also still running a set of 12" Road Thunder Pro with red rubber surrounds as my home theater subwoofers.
@@Bondovw your probably right, hard to say.All the legacy brands were bought and sold by conglomerates, usually bat the expense of quality. Coustic and XTANT are currently a Mitek( MTX) brand. It is likely they have identical guts to MTX products, manufactured in the same facility in China, and bear little resemblance to the hand made in America amp that Big D tested. Up until around 2000, MTX was a great, American made product. I bought one in about 02 from Circuit City.It was surprisingly cheap for an MTX, to my surprise, it was made in India, and it is sh!t(4004), I still have. However, in fairness, I have a pair of newer MTX, a class a/b 4 channel, and class D 500 watt monoblock , made in China, and they are actually pretty good and a good value ( Thunder series), Probably the Coustic is decent for the beginners as well. Personally, I try not to buy the Chinese amps or speakers, I favor the American,German and Italian products. I also have a Blue Thunder from the 90s, it is an excellent amp…made in Arizona, USA…those were the days
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
@@wal2 It seem these Arizona amp designers bounced around from PPI to PG or Orion etc, That is probably why the similarities.. I would love for someone to put in prospective ....write that book Big D! Probably many of you friends and fans can contribute.
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
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.
I’m from Louisiana I’m 44 years old and I’ve been into car stereo probably since I was 14. I remember installing a Soundsystem in my moms car before I even had my license. Being close to Baton Rouge a lot of people played Savar. They had the regular series then they came out with the rap series then they came out with the HQ series which was basically a playoff the Solobaric‘s. I ran 4/8 in my ranger back in the day from them. We had an audio shop here in town and everybody one of those M&M Godfather’s subwoofers. I remember a guy having an old-school mustang 5.0 with 415‘s the buildings would rattle when he would pass by. I guess you can say I’m all about SQ now but I still like to get loud every once in a while when I’m on an interstate Drive
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.
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
At the same time the competition from Rockford was great and at the time the punch amps were more expensive. But the punch amps came with power wire and fuse blocks inside the box. The cheap shop owner would remove the supplied cable from the box sell them separately
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 ).
There is a rapper/RU-vidr named crypt he has a list of music he allows people to use on there RU-vid channels maybe check him out U might find a few bassy song's
