US AMPS

I'm getting sort of a loud bass note when the amplifier turns on and I was wondering what could be the problem. It was a drop in install since I had an amp installed before this already and there was no loud turn ons with the other amplifier. Also, since I put the MD2 in, I'm getting a lot of noise through my speakers at low volumes. The noises go along with how my engine works (i speed up, noise pitch gets higher). The grounds are the same as I had before and I never had this problem, so does anyone know how to fix this or the loud turn on?

does anyone know where i can find a shirt for re audio/ usamps? thanks in advance

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

call me way behind with them in the last 3 years...can I get a quick course on whats what?

After almost 20 hours I finally got my system up and running. Integrating into a Factory system with a Navagation unit is a headache but I did it. I used a RF 360.2 to send the signal to my amps. I have not put in the AX-3200DE yet but that will be this weekend along with my RE MX18. So I should start off by saying this amp sounds amazing. I am running my stock speakers and it makes them sound soo much better than the stock amp. There are things I am hearing in my music that I couldnt hear before. The only issue I have is that when the volume is low or where there should be silence in the music there is HISSSSSS. I dont think its normal and I have identified the amp as th…

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

BTW flakko.. when do we get the info about the US speakers?

Ok I have two of these amps. One from 93 and one from 95. I have some questions about them someone may be able to answer. These amps have different boards. I assume because they are 2 different gens. 93 is a bit more compact than the 95. Both boards have the areas where it seems more components could be added to make them 4 channel. Is this possible or just dead spots on the boards? Next, I see conflicting info around the web. I realize these are 65watts per channel at 4ohm and that it is not reccomended to go any lower. Fine, good, whatever. I am wondering if they can be bridged at 8ohm. I have not installed them yet so I cannot test them myself. I see some pl…

can an re 15 be used for daily sub if so what would be the recomended rms power and sub box

So I may have fried my black usa50 today. I turned off the car and I heard a bang. I looked and checked everything out. Amp was really hot. No electrical stink to it. I haven't tried to fire it back up to check yet I wanted to let it fully cool off. The board and everything look good from the outside. I plan to see tomorow when I get off work if it still wont turn on If it is indeed fried can I still send in the old usamps for repair. This one is from 96-97. I'm not sure if flakko can lead me in the right path on this one or not. If not I will call sometime.

Just as the title states... Who wins in terms of SQ? In my eyes, the prices are comparable, and I've heard good about both. I'm leaning towards going with the USamps XT series over the GTO's... One major issue that shouldn't be so major is the looks... The GTO's a gawdy, and the XT's are plain & simple. Any thoughts or input on the comparison?

I got my 2 US AMPS in today...thought I might get a 3rd for sub duty although I can get by with the 2 amps I have...wondered if a USA50 would be enough to power a sub...a 10 inch...

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!!

i just wanna know if the xterminator series amps that can be found pretty readily on ebay http://cgi.ebay.com/US-AMPS-XT2000D-xTERMI...1QQcmdZViewItem are solid for the amount of power they put out? i know they dont do the bolstered claims that you see but thier actual power and build is it good, clean, reliable? or is this amp just nice looking trash all the way around? i did see the video of the guy explaining how the numbers are "raised" so that average joe has no idea what his amp is actually doing. anybody here owned one, or had experience with them? thanks for any info . i am not trying to diss us amps( i own two old school ones 400& 150) but do these newer ones…

In an industry where people are afraid to deal with the small guys because they always feel liek they are vulnerable and customer service will not be consistent I am glad to say that US amps is not a company you have to think twice about when buying your next amp. I had a problem with my md2..... sent it back in for warranty, received a call from Greg immediately stating that they were waiting for parts from their suppliers and that there may be a slight delay in the repair of my amplifier. Since they were proffessional about it I told them to just keep me posted and I would be patient. A very short time had passed when i received phone calls from Greg and Hector stating…

Okay, i just picked up a couple oldschool USA-400's (the 24" long ones) and im wondering what the real power ratings of these things are. ive been getting alot of mixed answers, and google isnt cutting it. of course ive come up with the 1200x1 at 2 ohms, as per manual. But ive been reading that these amps put out WAY MORE than this. unregulated power = 10 percent gain in each volt about. and other various gains. ive seen 1600-1800w at 2 ohms... 2kw+ .. amp stable to 1/2 ohm. etc.. but i dont even know what's what anymore. what is the real deal on these amps? ie: whats the benched performance of these things? i may run a pair of subs at a half ohm... or stick with t…

Hey guys, i've got an MD22 amplifier, and was wondering if it was capable of handling loads down at 1.33 ohms or lower without compromising the internals (3x 4-ohm components / channel / parallel)? I Realize that it'll void the warranty, but is it safe to run at these loads?

ok...got all ready to turn on the 600x I just got...did....nothing...then looked at it again....no remote turn on terminal...where does the wire go to turn it on.... the manual online doesnt show anything on the amp connected to the remote wire off the deck...or else I am not getting the obvious...haha.. cant believe I have to ask this...

Hi guys I just thought I would ask here to save Flakko from too many more of my Pms : XT-1600.2 / IS 2200: Are these pretty much the same (internal wise)? I keep being told by various people that the XT are brilliant but will not hold up like the other USamps will, do they mean that in a 'you can't play them in to lower loads than recommended as well', or is it a 'they are going to die on me before the other would under normal useage'? MD22: Hows comes they stopped this? Was there somethign wrong with the design? Is it worth spending the extra on the MD22 over the above XT if they're going to be under normal useage? Oh and something in for the above models in general: …

i was told straight from mr kim himself to take them down temporarily. all discussion will be continued at a later time topic was not deleted, it was hidden.

I read in another forum that it should be out in JUNE.Do you Know any details? Any specs? Dimensions?

Simple question, What is the input sensitivity on the Merlin series amps? I searched the US Amps website but couldnt find the info. I'm contemplating on buying an MD21 to power a pair of components, just curious what their input sensitivity is.

I need some info on what the knobs do on the side of my VLX-400. LMK guys.

I got 2 12 re se 12's in my house and one needs a complete recone and the other needs some ne tinsel leads(snapped). So any ways i talked to greg about three days ago and might be getting the recone in about a month just wanted to post some pics. So a little history about the subs my cousin had these i bought them off of hime with the leads snapped. My cousin used his epicenter past it limits and he blew one of the coils on one sub and it is riped from one side of the cone, the other sub is good but the lead snapped so i put something temporarily for the sub but i want the ripped sub reconed and the other to get the leads fixed and just thought i would let greg know. Talk…
