So happy to have one of my amps reviewed by you, Big Dummy!! Cheers..

[@K-Effect]

Excellent video. I wanted these amplifiers so bad back in the day but they cost more than my car at the time. Polished stainless steel with the brass screen…beautiful! Still one of the coolest style/designs around

[@wal2]

They say it’s polished stainless but man it sure looks chrome to me. Maybe a deep polish and clear tho

[@positrack99]

Lucky you passed on them as they are trash at that price.

[@dextermorgan1]

I remember that build with the Strokers in it. I saw it in other magazines back in the day.

[@mugendrewable]

... You really pulled on some heart strings with this video... Thank you, Sir. You started with the mention of U.S. Amps. I collected some trophies with these as well as MATTS. Sound quality. Prior to those came the four 2350DM's powering a Cerwin Vega real deal Stroker. One amp, one sub. For Strokers, four amps. Next up you showed an input panel close up of a JP34ab... OMG!!! I will have two of those arriving next week😁❤️💕😁 On to the XTANT. You really did not drive the point into your viewers heads that all of the options that were available as plug in daughter boards are what is available today out of box from any decent quality amp. Back in the day this was a one box option that covered all those boxes and rca's we had to deal with. At the time the concept was greatly MISUNDERSTOOD!!! The other amplifier manufacturer that was also misunderstood was BLADE. I haven't finished watching the video yet but I'm very curious to see what your opinion is of the sound quality😁, even though it is a sub amp... !!!THANK YOU CHRIS St. AUBIN!!!

[@danielhillwick8430]

I remember back in the day when Xtant amplifiers first hit the market. They were the hot ticket for the SQ guys. I did a full build using Xtant amps and jail audio speakers in a 96 f150 extended cab. It was a stealth install everything folded up in the back seat. The back of the seat was the amp rack the bottom of the seat was the subwoofer box with two down firing 10-in JL audio subs. When the seats were folded up you couldn't tell there was anything installed. It looked like a factory finish seat. Thanks Big D enjoyed the video it brought me back to the day.

Reminds me of all the BMW's in the 90's car audio mags sporting Xtant amps and JL Audio subs in a stealth install.

[@DamonDupriez]

When I had to bench test Xtant amplifiers for my reviews here in Australia in the late '90s the jumper system controlled input sensitivity was a real headache. I had to juggle input voltage to the power supply (via a variac) to get 12 or 14.4V and simultaneously monitor the waveform on the oscope along with the AC voltage on the meter connected to the outputs. Man that was tricky - especially pon the 4-channel! I also remember these amplifiers clipping pretty harshly on the waveform compared to other amplifiers. I was introduced to Jeff Scoon by Mitek owner Lloyd Ivey while at MTX Arizona in Jan 1998. Lovely guy. Xtant stuff certainly was cool and unique back in the day. Nice one Big-D.

[@wal2]

Thanks for the info, really cool 😎

[@FATHERSOFBASS]

So this amp was ahead of its time it had the options for everything that comes normally on almost any amp now sooo crazy

[@kswis]

I personally haven't had an issue reading the voltmeter and I LOVE when I can see amperage vs wattage in the same frame. The amp is way cool. I'd maybe even say it looks like a current high endish amp. Very cool n it did well considering how old it is. Cool guts, look, ect ect

[@wutupclegg6618]

This was the only amp where the company brought out a rep to train all of us, installers, on how to properly install and tune these things. After a few, you get the hang of it. You start to learn which SIPS to change out and which ones to use. The SIPS are the black crossover components.

[@weesebowski8651]

Over 20 years ago I wanted an Xtant system. The 10’s and subs I wanted along with install was about $2000. Ultimate electronics was the install but I never was able to afford it. But this is awesome!

[@jasonbear681]

Yeah..that's the first thing customers do when they take their car home from the install shop is Jack up every bass boost they can..then bring it back in 2 days with everything blown up..

[@volvo09]

Haha, yep, levels so high that even with the volume real low a pop from someone talking on the radio causes the subs to bottom out... I had a friend with a setup like that, it sounded terrible.

At least with these once installed the customer didn’t have easy access to the settings

I spent an asinine amount of money, but I was young and stupid. And it sounded amazing. I must have been an early adopter without knowing it, because I’m pretty sure I bought them in ‘95. They were absolutely gorgeous. Thanks for the review - it really takes me back!

Great video. I got one of these amps in '99 pushing a pair of JL 10W6 that were in a huge box for some reason. No one really knew anything about the amp at the time including me but it was definitely a hit.. .especially back then. I really don't remember exactly what happened to it. I'd be willing to guess I needed some trunk space after having kids.

[@sirsnappz5307]

One thing I noticed I like to see a huge jump in numbers for dynamic power but I swear all the best sounding classics have a very tight regulation…the Xtant the JL slash the PPI art series those are my favorites on original W6 subs…

These amps were the precursor to the JL Audio Slash amps. Used to work with these a lot when I was working with Mitek back in the mid 2000’s. We used to have massive supplies of the sip chips. Have the later model the X1001 in storage.

We tried very low ohm connection by adding a box with a couple of 10" subs that we were putting in his GF's car to see what they sounded like added to the 12's. It didn't complain and put out more power as the 12's were moving more with the 10's hooked up than without. Not sure now that it was the smartest thing to do but at the time people were saying that they were like the old cheaters and would handle it.

While they can make very similar power across different loads, one parameter that can't be overcome is that as the impedence lowers so does the damping factor. When Xtant was merged with MTX later, this amp would become the 8100d, or the 1501d, can't remember wich one.

I'm glad the trend of amps having modules, crossover cards and such didn't last. Was not a big fan of being sold add-ons that are required to make your brand new amp work. Another downside is this: try getting a different module to change the crossover filter frequency for that amp nowadays.

[@davelowets]

I knew that MTX had something to with Xtant... My MTX Thunder 7801 sub amp advertises "Xtant Technologies Cooling" on the top cover of the amp, and inside it has a large pyramid shaped heat sink with 2 fans on top that pull air through the sink. Sort of like the amp in the video, except that the air-flow is drawn in through each side, and exits through the top of the heat sink. MTX must have also had something to do with StreetWires, because it says "Connections by StreetWires" on the cover also.
