US AMPS

about the md 1d is supposed to draw 90 amps at 1 ohm1200 rms but how many would it draw at 2 ohms 750 rms..im guessing about 55 -60 amps,i really wanna stay away from a ho alt,400 bucks is alot of money for one,and i believe 750 rms a be good enough for everyday listening,need to keep my hearing

I have 2 US Amps Md3's strapped. My question is will both of the amps be putting out AC Voltage or just the master? I went out there today and on music my master was putting out AC volts but my slave was not putting out any AC volts. Both of my subs work and they are wired seperate so both amps are working but the slave is not reading any AC voltage.

Any input on this? Any bench numberson the md3? I can get the MD3 bout $150 cheaper than the Kicker and it would be from an Authorized dealer while the kicker wouldnt be. I plan on running four of either amp each to a 15" hdc3

Hey guys I was curious if anyone had any idea what a US Amps 3000 de 2006 model should sell for. It is still new in the box. I have one that I will be selling and would like some idea as to what to expect. I was going to use EBAY but after looking at amps there I am thinking twice. Any help would be appreciated. I dont want to lose too much money on this if possible. Thanks. Charles

well in terms of the class D's....greg just told me that they use the same circuitry as each other. as for the A/B amps, they are totally redesigned, the USacoustics redesign was scrapped, and are now lookin like the old Florida amps. i guess the only difference is the AX line is infinitely strappable. so yea thats GREAT news to hear im thinkin i might go all merlins next.

the md 1d is rated at 1200 @ 1 ohm but at how many volts

Trying to decide for subs.I am going to put one to a (two subs two amps) 13w7.What is the difference between the merlin and the Ax line, I know that the Ax line is the top line but how comparable is the merlin line

ok ive decide to go with the merlin series d class .its either the md.1d or the md.2d, i here the 1d is overrated and then that it will do exactley what it says it will,then the md.d2 i aint ever heard its under rated .. i heard it could do about 1800 watts @ 1 ohm.how big of a difference are they,is the md.d2 worth several hundered more?,ithan i noticed on here it says the md d1,2 and three all have 30 amp x 3 fuses,that aint true is it?hows it gonna give more power without more amps coming in,the effiencey should be the same since there same series and class

I have trying to compare the MD.1D and the XT-2000D for a Q15 I hope to be getting soon and other than the price, I haven't been able to tell the difference. They put out the same power and the other specs I have seen have been comparable. So why the difference in price? Also, is it correct that each of these amps put out 1200W. The US Amps site says 1200W for each, but I have seen some say 1000W, some say 1050W, so I don't know what to think. Thanks for the help guys.

I just checked the specs on this amp and it is not very high only 200 if I am correct.The JL amp is something like 400 on damping factor.Can somebody correct me if I am wrong.The higer the better if I am right.

Do they produce what it says??? Or over/under rated??? xt1600.2 200 watts rms xt4000D 1500 watts rms Thanks

I have 2 of them strapped powering my AQ HD3 15's. I am running them off of a Kenwood KDC-X891 HU. The only problem I am having is when I start my truck I get noise through my subwoofers it is more audible when I first start my truck and when the HU is loading the CD. Then it tones down a little bit once the cd starts to play I can not hear the noise anymore because my subs are playing the music, but then when I turn my truck off I have a turn off thump. Is this something to do with the HU or the amps? I did have 2 Viper 1200's strapped before the MD3's and I was running an Eclipse CD5435 HU and I did not have any turn on or turn off noise. Since then the Eclipse HU's RCA…

I just got a US Amps USA-442 and I was wondering what kind of info can you guys give me on it, power that I should expect, how good is the amp, you know things like. Help me feel good about my purchase . Also, I understand that it has a very complicated built in crossover, can someone help me out with this also? Thanks

Has anyone benched one yet to see how much power they put out? I am wanting to know how much continuous power they have been tested to put out at a 1 ohm load, before clipping, at what voltage did it put out that power, what THD, etc. I just want to hear from some people that have actually tested them

All i can say is WOW... just wow. im a believer Jim, ima believer. the music got louder, more detailed, and most importantly it doesnt clip! i have to listen to all my music again tubes forever. i cant believe im only getting around 100w from this amp... but one thing is wierd...sometimes when i change tracks, the amp doesnt kick on... gotta wait a few seconds, and it comes on. i dont know whats up with that.

Will these amps do rated power? I have heard mixed reviews about the power they put out some say they will do the power plus some and others say that they will not make power. Also how is the build quality I have heard that they have went downhill compared to their older amps. And if they do rated power at what voltage do they achieve it, I am assuming 14.4 which I will never see my truck idles at 13.8 and runs at 14-14.2 at 2000 RPMs also how efficient are they? Pretty much are they worth the money or are there better built amps that do more power for the money?

I am new to the forum but I am upgrading my amps and I need to know is the AX the top line and what would be the best amp for a JL 13w7 I am looking at least a 3 ohm impedence no more than 1500 watts.Has anybody heard a 13w7 to a U.S. Amp.I need to know as much as possible by one day thanks

I hooked them up using the MLT, linked together, and I can not get them to push my 2 AQ HD3's with the same power. I have tried everything I know to tune them but they will not push them with the same authority. I can get them to be working the same on a test tone but whenever I play music the subs do not hit the same frequencies with the same authority. One will hit the low frequencies good and the other will hit the mid to high frequencies better. What is going on? I tried to turn all the gains to the same point but that just makes one sub hit hard and the other one will be lagging. What should I do, I tried to unlink them with the RCA's and have them acting as single a…

Just trying to get my power down. I know the MD2 are rated at 1500, but push closer to 1800. Do the MD1 push much more than 1200. I am trying to decide if MD1 is enough

ok as the title states i am wondering if the md3d is .5 ohm stable because i going to be running 2 12" SX which is dv2 so my ohm choices are .5,2,8. and the electrical system i have is this, 200ish EA alt, 34/78 yellow top, 2 hc2400 and is all wiried with 1/0 guage wire, and also 1/0 big 3.

Hi guys, new to the forum... just looking for some input from people that are familiar with US Amps and RE Audio. I just dropped some cash for my new system, and was curious about your opinions on my choices. I haven't installed anything yet except the deck as the amps and cap won't be here until next week: 2001 GMC Sierra Stepside - (STANDARD CAB!) Head Unit: Pioneer BT9800 (Bluetooth rocks on this deck!) Subs: 2 RE Audio SE 10 inch (new logo) - will be wired to 1 ohm Enclosure: Custom Built Sealed @ .65 cu ft each (optimum according to RE) - 3\4" MDF (Air tight, trust me!) Sub Amp: US AMPS XT-4000d (2007) Front Doors: Infinity Reference 6.5" Co-axial (Existing, curre…

Most people around here know I was running (2) MT 18's and (8) MD3Ds. I am now running (4) MT 15's with the same amps. Each pair of amps is strapped to a MT with dual 1.4 ohm coils in parallel (.35 ohms per amp). With a hour of testing, I was able to pull a 157.1 at 37 Hz with the new (4) 15" setup. And it will actually do 157.0 from 36 to 40 Hz. The (2) 18's did 156.9, but that was at 43 Hz. I will post some videos of it in the next couple of days. Anyone know of a good bass race song @ 38-40 Hz? Brian

I've got an older USA-2000x which is the 2 ohm stable model. Say if I ran this at 2 ohms bridged, would I be good with a 200 amp alt, Kinetic HC2400 and HC800? Thanks

Hey guys. I am looking at this Usa-100Hc and I need some specs on it. If I was to get it I would be putting around 14.4 volts to it..I see at 1 Ohm it is rated at 800 watts..Do you guys have any info on it? I have done searches, came up with minimal material..Wanted to talk to the Us amp masters...Oh yea it is the Old style Usa-100Hc if that helps..The longer model...Thanks guys..Also would it be a better amp than my current Xt4000d??? I love the old school amps..

Hi I've been calling around to different car audio companies accross the US and all of the stores tell me that mmats amplifiers beat us amp hands down. (compared to merlin series) Is this true? I know the car audio shops have installed both amps and should know, but this is a us amps forum and wanted to hear if there was a difference in opinion. Has anyone here dealt with mmats pro audio amps? thanks
