awesome power,good construction in and out,doesnt make u go homeless signal to noise ,makz its power at 12.9 volts not 14.4

features,cooling fan would be nice for trunk installs etc.

Apparently some people do not know how to hook up amps,i have a 2100&2150.2150 is running 2 infinity perfect twelves.2100 is running a infinity kappa mid and tweet package.u cant' ask for better quality and power and sound quality,especially for the money.in the past ive owned rf,kenwood,soundstream and orion.this is comparable except for maybe features.the power and quality is there u just gotta be able to hook it up correctly to get it.i got 2 U.S.a.C. trophies to prove it

rates up there with rf orion and kenwood

It's grey

This thing SUCKS. I had it running a 15" JBL woofer.. It was supposed to put out 300watts RMS at 2ohms, but it sounded like crap. There was hardly any power pushing this thing. I was better off running it as a 2 channel amp. Here's more crap. 1 RCA plug-in snapped. You know that plastic thing? This amp is really weird. It's definitely underpowered, the construction is crappy and it was a waste of money. It's sitting at my house currently and not in my car because it's a P.O.S.

I paid like 200 for this thing. well, okay so i didn't pay for it. someone else did. I don't care since it wasn't my money. BUT if i was you? i'd stay away from this AMERICAN MADE product.

JBL, Profile (even this crap amp was better than the USAcoustics)

0-18db bass boost, crossovers that work. believe it or not but it is running my 2 jl w-0 12" subwoofers @ 2ohms mono, and puts out an amazing 500 watts rms or 250 to each rms.

tends to get warm over a 3 or 4 hour period of time and abuse.

This amp is the best bang for the buck that you will find anywhere. Pushing 2 12" jl w-0's @ 2 ohm mono and 250 watts rms per sub is a deal. crossovers actually work at right frequency, and bass boost is always a plus. If anyone would like to buy this usacoustic 2100 and 2 jl w-0's email me at Remsmx6@aol.com.

none that i have found

very strong performance.

It does need an internal fan.

The usa 2100 was and will continue to be the best amp I've ever owned. The one I had put out more power than it was rated by 69.78 watts. That was on top of the 300 watts it was supposed to put out. I had it hooked up to 2 JL Audio 12W3's and it pushed the like there was no tomorrow. I would still have it if someone hadn't offered me more than I paid for it after I'd had it for a year. So if you can find it cheap buy it, it worth every cent!

crossover, bassboost, power, sound quality.

blew a couple fuses.

i've had mine for about a month now and it has done very well so far. for the people saying it sucks and has no power they must not really own one because mine is pushing two Rockford punch 12's and it makes them hit harder than my friends(who also has two punch 12's) MTX amp which has more watts. it is a good amp for the price and i would recomend it to people who want big bass but they don't want to spend their weeks pay for it.

it compares well to many MTX amps that are around the same size and some kenwood amps.

good amp for the price

it gets hot very quick

This is a good amp for anyone who is on a budget. Crutchfield has them for $180. The only bas thing is it heats-up quickly to the point where you can't even touch it. I don't think is realy puts out what it says because my pioneer amp is only 150 watts RMS and this amp is 300. It doesn't sound anywhere near double the power of my last, but I use it anyway and I'm satisfied

its better than crossfire

This amp offers incredible performance at a very low price. It provides a good amount of power bridged.(300 watts rms) The bass I get from it is very clean and tight.

There Really aren't any

I paid 200$ for this amp and think that it is worth every penny and then some. I have it running a dual 10" JL powerwedge box. The bass output I get is incredible. This amp is capable of playing extremely loud and plays very clean. I don't car what anyone else says about these amps, they are absolutely phenominal. This is in my opinion the best amp value out on the market today. I recommend this amp to people looking for great performance whether you are on a budget or not.

MTX, Crossfire. The USAcoustics amp is a better amp in my opinion than the MTX and probably very similar to the Crossfire. But for the price it destroys both of them.
