US AMPS

I see two different md2s' One says "Merlin MD.2" and has all of the connections at the bottom of the amp on the long side The other says "MD-2D" and has all of the connections on the right end of the amp (this is the one on the usamps.com site durrently) The power ratings are identical, but there is no way that with all of the radical differences they are te same, one has to be better My questions are these; What are the differences (is one like a 5 year old model and the other current?) And of course, which one has more power! (do they exceed rated power or just meet it? at 2 ohms specifically), Does anyone have specifics or no? And what else about them should one know?…

Anyone know if the RE SX will run 12 - 1500 rms daily?

Funny, as I am waiting for my USA-600x to arive, I had to put an Old Rockford Fosgate Puch 100 DSM in my car. Well early this week I bought a US Amps USA-50 as an amp to run my tweeters in a all active system. I just realized its rated 50 watts X 2 just as the RF 100 is alaso rated 50 X 2. I am going to get some connectors tomorrow to properly attach the wire to the US Amp and swap the two. With the same power rating and similar size, I look forward to seeing which one takes the cake lol On a side note, Can anyone explain why my USA-300x I just got has 2 Power connections and 2 Ground connections? Do I need to wire accordingly? If so that means even more distribut…

hey guy my friend wants me to buy his us amp 50 hc but we dont know the specs on it. does any one know them? is this amp any good? -Thanks

Is this amp still made? if so where can I get one? and price on it?

her name is Michelle, friend from chuch. she speaks PERFECT english! so no more complaining about some asian dude answerin the fone haha. treat her good yall...

Hello When will the 2008 be out or are they already out? And what will be the difference between the 2007 and the 2008 merlins calss D amps? Thanks

Many people say that the old school us amps were better probably because they were made in the US.At least in the 21st Century how good or bad in terms of circuitry are the amps compared to old.( I know US Amps AX Line are made here)

lookin fer 70ish x4 @ 4ohms lookin fer 500ish @ 2 ohms and 1000ish @ 1 ohm as small as possible? dunno if thats possible now adays... large power, small foot print, like my rf power series amps... have to be same US Amps series... jeremy... do ur job =D

I have this US Amps 200, looks to be made in the 90s, no crossover. Works great, but gets kind of warm running bridged at 2ohm. I recently got a Ascendant avalanche and those subs come in dual 2ohms so i was thinking about running the amp at 1ohm bridged. I've heard from some people that its possible with a little modification, i'm no electric engineer, but i've modded a decent amount of ps1/ps2 and built some headphone amps so i'm tempted to try this. Besides swamping the capacitors w/ higher voltage capacitors, what eles could i replace on this amp? Is there anything i can add? Could i just leave it as is and just cool it better? thanks in advance for any help

I have a USA-200 pushing a 12" RLP on a single channel at 2 ohms at the moment. From my understanding the 200 is bridgeable at 2 ohms. This is one of the first usamps I have owned, and I am unsure of which terminals to use for bridgeing. Anyone know if it is the right + and the left - or vice versa, or if I am completely wrong and the amp is not bridgeable @ 2 ohms?

Hi, I'm looking to buy a new a AX-5600, and I don't want to pay full retail for it. Can someone recommend a dealer that will take care of me at the right price?

Now I am not going to point fingers at us amps quality because it is probably me doing something wrong. Anywho, I have a us amps xt1600.4 runnning focal polykevlar 5.25" components. I have the focals in stock door locations with the tweeters mounted on the pillars. The xt1600.4 has a .5 farad cap on it. I have not yet fine tuned the gains because i have not had the chance but they are roughly set. I expected this combo to blow me away, but it is not any better than the old boston component set I had running off the HU. My question is: Could the gains need to be changed, I mean, can that cause distortion? also, I have some sub par rca's from scosche. Could that be it? Last…

Hey, US Amps owns RE now right? Question on an RE purchase: I found one of the SX models on eBay for $209 while woofersect.com costs $420 on sale http://cgi.ebay.com/RESONANT-ENGINEERING-S...1QQcmdZViewItem Is this just because there's no warranty and it's a shady dealer? or is this an older model possibly? Thanks for any info

Hi all, I am still waiting for my US Amps to arive, and in the mean time I am ordering new wire and other things I will need for my new install. I have 0 Awg comming from the Battery back to the trunk. I will be running a USA-300x, USA-400x, USA-600x and a USA-50. Should I run 4 or 8 awg wire to those amps Power and ground? Also should I run one large fuse, or get a distribution block with seperate fuses to control each individual amp? Just wondering what wire and hardware I should use to insure a strong safe system.

What makes a AX2000HC worth $1000 more than a AX2000? I know that volts x amps = watts. I have been told that a AX2000 produces 600 watts at 4 ohms and that a AX2000HC provides 150 watts at 4 ohms. I don't understand. Does the High Current amplifier have a extremely low voltage? Does the AX200HC have a much better power supply contained in the same size package? What IS the difference? I know from experience that US Amps builds a heavy duty amplifier, but specs don't help me understand what I am getting for my money.

Look at this think lol........ http://cgi.ebay.com/USAMPS-100HC-Super-rar...1QQcmdZViewItem

I'm looking for a U.S. Amps Optimizer. Anyone selling one? Anyone ever use one? Is it worth it? Does it do a good job.? What do you guys think? Let me know please.

Hey guys ive had an AX4300 for about a year now and one of my channels doesn't work properly. It seems that the rear right channel will give a very scratchy sound like the speaker is blown. i went back and checked the RCAs and they were plugged in fine. if i jiggled the rca or pushed it in harder it would clear up for a while but then the sound comes back. What is going on and how can i fix it!!?! Thank you

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

I just purchased a set of XXX6.5 components from RE and would like to run it active. Would you guys be able to give the the ideal crossover points at what slope to run the mids and the tweeters ? There was no white paper/specs that was included in the box my gear consists of Alpine 9887 Audison VR209 (200w x 2 @2ohms) to the Mids Audison VR203 (70w x 2 @2ohms) to the tweeters Audiosystem amp 780watts@2ohms RE SE12 @ 1.1cuft sealed box Thanks and hoping for a quick reply

this is probably dumb but this is my first us amp and i noticed that on my md1d there are 2 channels even thought it is sold as a mono amp. my question is most amps i have owned had the bridged output marked on the amp. this one doesn't. can i just use a positive off one channel and negative off the other? does it matter which? thanks in advance for helping the newbie.

okay this will be the official USAmps picture thread.... you got some pictures? post em here is some news: * New and improved AX Line * Unveiling of a 6 ft. long amplifier (note: upon further questioning, this "amp" at the show is just a giant heat sink, showing the possibility of the Multiple link technology. this is NOT an actual amplifier, just a chassis) Larry, you were right. * Brand new Xterminator Line to replace the IS * USamps drivers and comp sets (TB released in the future) thats all i could think of so far. im going to get some in depth info tomorrow. pix from Djjdap courtesy of 95stroked1500: the new Xterminator line to replace the I/S WOOT! HMMM usamps…

i need a us amp md2d very very soon for the 15s, who knows where i can get one from for cheap would really appreciate it trying to spend like 350 checked ikesound they had one for $299 but the pic didn't look like the one i want but the title said it was right so please help

I am just wondering how the new XT series and VLX series amps are compared to some of the amps from the past. I am looking at these amps and they are a steal for the power they claim to put out and the efficiency they claim. If someone could tell me how they are now I would greatly appreciate it and also if someone could explain to me what some of the differences are between the VLX and XT series amps are because spec. wise they look very similar but their is a $100 price difference.
