I have an old school Memphis pb 600.2 I can't find anything about this amp. It needs to be repainted. I really want to get amplab to repair it and have you test it and pull up any information about it in case someone else has the same amp and were in the same boat.

So take a classic brand name like USAMPS, build it in China, and charge over $1000 for it?

[@NvTwist]

One of my proudest demo/SPL builds was a 94 LT1 Caprice Wagon, 10 USA-50HC amps mounted vertically so all 10 were seen thru rear glass. Rear seats were evicted by a wedge of 20 JL 12W4 Subs, 10 on top 10 on bottom. Each amp drove 2 subs wired for 1 ohm bridged. Man the 90’s were some of the most elaborate over the top steel installs, nobody builds motorized amp racks that hide everything these days it’s all just plain Jane static equipment. 🎵 “Those Were the Days” 🎵

[@evilinside5984]

@NvTwist- Awesome setup you had. Did you ever hear of, or see a guy who had i think a walled Honda civic, with 16- 12s in the back seat area, and a trunk full of US-AMPS Amplifiers? I got to hear that thing @ a shop in the 90s, it was Awesome! I think he did a 160Db, on the old meter= prob. a 152 to a 155Db on a Term Lab. Did you ever meter your system?

[@NvTwist]

@@evilinside5984 oh it wasn’t my vehicle it was built as the shops sales/demo/ShowCar. Even thou the amount of power and number of subs normally seen in DB Drag/SPL/Burp stripped interior competition vehicle’s the wagon install done like stealth SQ builds. Well um semi stealth, the only components not hidden were the amps heat sinks and the wedge wall of subs. Massive bass to draw the crowd the clean install brought in the customers. Favorite trick to show off the massive power was to place a Sunday newspaper on the dashboard roll up window and close the doors and do a quick full power burp that effectively making it the fastest paper shredder ever built, instantly shredding the paper flying thru out the entire cab. A crowed pleaser cause everyone enjoys watching carnage.

[@v12alpine]

When I worked at a stereo shop in the 90's the manager had a side project with 18 polk DB 10's in a rear seat (removed) wedge on a 92 thunderbird. Two cessna alternators and 9 alpine V12's. I would not dare sit in that thing. Pink panther theme song (revenge of the pink boom) was the theme song lol.

US amps were the envy of so many back in the day. I managed to get a hold of a 100HC and then it took me months to get the electrical system in my 1977 Ford Maverick able to handle it without the headlight dimming. My buddy had a 200HC and a 100HC. Crazy times, good times and man, back in those days the bump came before the groceries.

I worked for a custom install shop in the 90's... we had a US Amps 100HC on our demo board. I could literally activate every single sub cabinet on our floor (about 15 cabinets, maybe 20-25 subs total) all in parallel, and it would just play right through it. Always astounded me.

[@StonerCreek74]

We didn't have U.S. amps where I was, but used to do the same in the early 1990s with the Soundstream Reference 500 at our store. We had like 16 subs, and it would run them all in that demo room. We sold alot of those demoing them that way. Miss those days!

[@RichInMN]

@@StonerCreek74 Good times my friend

[@wal]

That's crazy

[@evilinside5984]

Back in the day, most subwoofers were either single 8 ohm, or single 4 ohm coils. Installers are usually pretty smart. Multiple Subwoofer, demo show room setups, of up to (32)- single 8 ohm voice coil subwoofers, could be ran on the 1/2 ohm stable High Current Amplifiers. Each pair of single 8 ohm woofers in series= 16 ohms per enclosure. Parr. all down to 1/2 ohm, & no one knew about impedance rise back then= 1/2 ohm @ rest, would rise on average 2x to 4x, on music, so 1 ohm, to 2 ohm power. Heck, even if they were all single 4 ohm coiled woofers= 1/4 ohm @ rest, & prob. 1/2 ohm, to 1+ohm after impedance rise!?

Good lord did this bring back memories. As a car stereo nerd born in Gainesville, FL. (home of US Amps), I was always so proud to have their amps in my rides in the mid 90's. They were never flashy, but they were built like tanks and produced some serious power. I still remember the industrial park they were located in. It was cool to visit the exact spot my amp was made in.

​​@@raymo6795a good/well designed class d amp will specwise maybe have 0.001% thd while a class ab could be 0.0001% thd rated, but push either and they will have more thd either way also imo a good class d amp distorts the audio less than a class AB amp and amplifies it more cleanly overall, the reason some people prefer AB and tube amps is because they actually DISTORT the signal, especially tube pre/amps they also consume far less power

[@clntuning]

It’s great to see US Amps coming back and building these amplifiers. People talk about nostalgia and all these other things. I think this is down to each person‘s preference and what they want from an amplifier, I am an AB amplifier guy. I know there is a perceived sound difference between an AB and class D amplifier. That can be and has been debated in many other places. I would be willing to spend the money to get an amplifier like this because I feel it is a better-quality unit. There is a group of audiophiles out there who are looking at sound quality over SPL. This is more the type of amplifier for them because you have a ton of power for Mid and Highs.

[@iwiredit]

I had the US Amps 2000X class AB on two 15" HCCA Orions With a high output Alternator and in the winter time when the volts got higher, Id start my truck in the morning and see 15.4 Volts on the dash and the amp would NOT turn on until the voltage went down to 13.8. Sometimes it would take 20 minutes to kick on. Great amp and lots of power. I think they bench tested it around 3000 watts rms @ 2ohm, But it not turning on was so annoying because of the high voltage that I ended up selling the amp and switching over to class D. Never had the problem again. Them amps dont turn on if the voltage is to high. Once it turned on then it was fine. But I couldn't be patient, so I sold it.

[@Tron1731]

Hands down best 2 channel amp yet I love full range 🙌 amplifiers

[@CrazyWillification]

Really feel like they came back because JP is now winning in this segment and they clearly are unable to compete. I feel like they really dropped the ball. Friend of mine had one in his Del Sol in the late 90s powering 3 JL w6 (V1) in his trunk. I also worked at Circuit City and knew about them. I stupidly ran MTX but oh well. I know better now. Great job BigD~~~

I have always saw the "use head phones" in your videos, but don't usually have them handy. I use the speakers in the TV that I use for a monitor in the house. I pulled my Polk M20s from my boys room (he doesn't use them), and put them in my garage running off of an old AudioSource AMP One/A set up in a near field configuration. I can finally say those little Elacs sound good.

[@williamprentice9539]

I remember paying about the same for a US Amps 400 many years ago. I think it did around 1200 at 2ohm bridged. I ran 4 15 inch Kove KXP pros off it. So loud and clean. I’m glad they are trying to make a comeback 😃😃😃

OK, one 375Amp alternator, 1/0 cable, a lithium cell bank, and some Ultra Caps. Got it. Class AB. Actually, its efficiency was quite good at 4Ohms and 2Ohms. 2ohm was still the theoretical typical Class AB efficency of 50%. I don't like pushing anything. I would keep it at 4Ohms because that turkey was getting warm. Like the HiFonics Eros Series VIII gold edition we had at between 2 and 3 Ohms mono during a nice humid July night, blasting.

Is RE Audio back too?

[@bobdodge3171]

Ya but will it catch a pencil on fire? Like they showed in the 90s.. they been back for awhile now. Also Orion is bringing back the NT. Slightly upgraded with inputs and output connectors. Those are running $2500 each. So this US AMPS is a bargain.
