US AMPS

Is there any way I can get schematics for an old USA 2000X, USA1000 and USA-150? they all need repairs and being the other side of the pond in blighty I'd rather repair them myself. The USA 150 has smoked some FETs and PSU diodes. The USA 1000 cuts out intermittantly (could just be a dry joint) both those have been abused a bit in the past (not by me, I'm trying to bring them back to their former glory and give them a good home) The USA 2000X was reverse polaritied by a moron (along with the rest of my car when he tried to jump start it) and now has PSU/system noise appearing on the audio, probably jsut a diode gone somewhere but schematic would make it somewhat easier t…

Hi, I'm from Germany and I have bought an US Amps Merlin MD-23 Amp on Ebay earlier this year. I never opened it because I didn't have time to work on my car. Today I finally wanted to look inside my new Amp and I was shocked. On the Packaging Box and the Chassis it says MD-23 but on the Board it says MD-22. So I guess I was deceived by the Ebay seller. But I wanted to be sure, so is there any attribute that could tell for sure which Amp I do have here? I'm looking forward to any reply you can give me =) Greets Eric

I've got an offer for a brand new MD.23 for $250 shipped....I'm guessing it doesn't have a warranty..? How do you US Amps hold up? Do they tend to break down a lot or are they pretty stable? I would buy with warranty but its almost $450 more than this guy is offering for from my understanding...the price of an extra 2 non-warranty MD.23's. Does anyone know where to get these for significantly cheaper than $700 and still have a warranty? Regardless of the warranty, how do you like the Merlin line itself? Is it a big step down from the AX line? What other company's amps does the Merlin line compare to? Have any of you guys used the MD.23, or are you familiar with it a…

USA 800 Did they come with a X-Over new I have heard there were only 50 produced is this true and if so was it in 1999 roughly.

was wondering if i can strap 2 of these amps together???

I absolutely loved the old school USA-2000 I used on my front stage at 8 ohms a few years ago. But, now that I have sold all four that I had (like a nutcase!) I am interested in what would be as good or better in the near future. I am considering switching to a 4 ohm load so I am very interested in the old USA2000x. My questions center around comparing these models to some of the newer lines. Would I be better off with the amps mentioned above or something like AX-1000, AX-2000, MD23, or maybe some similar 4 channel models bridged to 2? I have been thinking old school the whole time because I haven't kept up to date on the new stuff enough to know how it compares. T…

hey yall im looking at purchasing a US AMP and want to kno which one do yall recommend: this USA 400 http://cgi.ebay.com/US-Amps-USA-400-2-chan...1QQcmdZViewItem or this DE1000 http://www.speedsound.com/product.asp?specific=jnirnmdng am mostly interested in an AX1000DE if any knows where to get one but for now which do you recommend.

Hi all, I'm new! My name is Francesco, from Italy Two questions: 1. Where I can find U.S. Amps IS2150 Manual? 2. Today I tested it but there's a little problem... If I put signal on right input channel I find speaker output on left channel and viceversa! The board is REV. A. Is possible that the IN-OUT RCA serigraphy is wrong? (Normally RED is right and WHITE is left...) I also find some distorsion on both channel but i'm not fully sure because I used only a 200mm woofer. Power cable in photo is just to test it..if it works I give it a 2AWG Some photos: I hope you can help me, thanks in advance!!

well, i talked to JR today, and i got some cool news. along with a cosmetic makeover the new MD1 MD2 and MD3 are all class DE like the AX's, as well as strappable (finally) the XT2000D and the XT4000D both have 20% more output and are using 110v (i think) power supplies instead of the original 70v next time i stop by usamps ill try to snap some more pix of the new Merlin sexiness. more updates to come as they show up.

I'm currently running a rockford fosgate amp to a single sealed rli-8 s4 directly coupled to my cabin (via the ski pass hole). The SQ is great, but at higher volumes I think the amp is not so clean. I've got a 1 farad cap and battery is in the trunk, and my radar detector displays system voltage and it's very stable. I was thinking of replacing this amp with a XT 800.2. I think is is sized appropriately. The Rockford Fosgate I'm running is the previous generation of this model: http://www.rockfordfosgate.com/products/pr...S&p_status= Sound like a plan? TIA! -Ron

I've searched all over and have found only a little info on this amp. I do have the white pages. Any and all info would be greatly appreciated. This amp should be very flexible for the install but I'm not sure how to use it best.

Does anyone know ANYTHING about this amp??? I have been looking and cant find too much info on these at all. I know that it supposed to do 3k @ 1 ohm, but thats about it. I have an opportunity to get two of these blown (not burnt) for a really good deal but I need to get all the info I can first. I also want to know if these are meant to be run strictly at 1 ohm or can it go down to .5. Any info good and bad will help. Thanks

I have a US Amps USA 800 pushing 4 15's I also have 4 Zapco C2K 9.0's in the closet, My ride has Zapco on the mids and highs so I am going to put the 9.0's on the subs. I think the information on this amp(USA-800)is interesting for those browsing this forum and I'm checking to see if there is enough interest to warrant selling it. The following is a portion of the ad from when I purchased the amp. -------------------------------------------------------------------------------------- Here's one I'd be tickled pink to find under my Christmas tree...one of the original 50 US AMPS USA-800!! This is THE bad-boy cheater amp, with sound quality creditials. Truely the absolute be…

Damn! So I was bored and did some research on where i got my RE's 3+ years ago. So I have heard the cars and everything #1 dealer for sho! I'm pretty sure most people might know it, from my understanding I think RE started right their...wel some pics.

Does anyone know where I can find an owners manual for this amp? I find conflicting info about it online.

I have this amp and it worked well until i let my friend borrow then i got it back and it doesnt produce any sound. The first thing i noticed when i turn it on is that it makes a clicking noise. I know what makes the noise its the black peice in the picture. it powers up but no sound comes out. What is THE piece and has anyone had this problem also is it fixable? I also noticed that if i set the input voltage to 9.6volts it wont make the sound, but when i turn it up above 9.7 it clicks. even at 9.6 volts it won't work. Also it only makes one click like a fuse and makes it when i turn it off. Also the little white thing in between the 2 big black circles, i dont know what…

Just sent this to "tech-at-usamps.com"

Has anyone ever tested it to see what it really puts out? i know most people say us amps are why under rated but since i have a 2000x i wounder by how much.

I'm interested to see how much this amp would cost Also want to know how much a MD2d cost, thanks a bunch Trying to decide on what amp I'll buy.. Thanks!

So I finally got this beast of an amp. I looked at the user manual but have a question on wiring. I will be using four single 4Ohm subs. The way I understand the Manual I can wire two subs together to form a 2 ohm load and use one set of terminals on the amp and do the same with the other two subs for the other set of terminals and the amp will see a 2 ohm load? My head tells me the amp would see a 1 ohm load but the manual makes it sound like it would see a 2 ohm load. Can someone help? I would prefer to run at 2 ohms VS 1ohm but if needed will run at 4 ohms as to not destroy the subs I have. Subs can take 500-700 RMS.

Consumer came over to pick up his MX15 from repair and wanted to hear the EXPLODER so I gave him the full tilt ride

I plan on purchasing this amp very soon to run my planned active front stage setup and I would like to know how much power this amp puts out at 8 ohm and 6 ohm. I also want to know just to be sure would I be fine running 2 channels at 8 ohms and 2 channels at 6 ohms with it. Thnx in advance to any and all that can help me out.

I have so many US AMPS and I like them a lot. They are loud and shiney and sound great. The plexiglass bottoms are ingenious. They really add to the character of this well built amplifier. Just thought id share. I have been through my fair share of USAMPS. I even have some for sale. Ill be selling them even on this forum after I accumulate 25 posts! What do you guys think of USAMPS? Here are some pics of some of my US AMPS. Beautiful arent they?

i heard my 1st re sub the other day. it was the 18 xxx from 2007 i believe and it was running off a saz3500 in a 7.5 cube ft box. i must say im glad that i wasnt the one that paid for it. imo big disappointment. the guy that owned it actually took it out and put his set of 12inch rockford p2s back in his car then put the sub on craigslist for half of what he paid for it 2 days after buying it
