US Amps 2000x Need opinions ASAP

[gymdiver426 10+ year member]

Hey all, I just want your input on some things in regards to an amp I have.

Let me first start off with describing what I currently have. At the moment I have a Boston GT-50 5 channel amp powering my 4 JL-C5 doors, 2 SoundStream 12" T4's which peak at 1200 watts each. I recently came across a Us Amps 2000x amp unfortunatly the amp was blown.... My plan was to replace my 5 channel Boston GT-50 with This 2 channel Us Amp and use my other 4 channel (Boston GT-42) for the doors so I would get more power out of my subs. So I sent the Us Amps to Zed Audio Corp in california to be quoted on a repaired. I recieved a call for them today and they told me the power supply is blown and the amp is blown and that it would cost $300 to repair.

Now my question to you guys, is it worth repairing this amp? I've heard good and bad things about this amp and the company Us Amps. My second question is how efficiant, reliable, and consistant is this amp at 2 Ohms (1000 Watts per channel) I dont want to end up paing money just to have it blow again after a year.

It is good clean class a power,however a power hog.Class a amps will run hot,especially that amp at 4 ohms bridged.Pm me a sale price as is man.

Yea I'm prepared to add a second battery and maybe a new alternator if need be. And I'll let you know if I want to sell it.

A few dollares more, and you can get a great made amp with warranty,that delivers power,and has proven itself.May be a wait, but you can still run that 5ch mode till it comes in/just my 0.02cents..BNIB with Warranty

Mostly interested in what people have to say bout this amp before I consider buying a new one.

I ran a 2000X with 2 12" Premier TS-W2000SPL for quite a while, best class A/B amp that I've ever used. I even used it to run a set of component speakers and the sound was hella clean. Yes it does run really hot, yes it is pretty inefficient but it is an awesome amp. The 2000X was one of the most powerful amp on the market when it first came out ~12 years ago, these used to post up in the lanes cooking up great SPL numbers, but it is getting to the point where technicians don't like to fix them (everyone said it's a PITA) and there are more affordable class D alternatives these days. However, this amp will beat down any 2000 watts RMS amps from today, and probably kick their dog too.

I still have the car audio magazine that tested one and they got:

12.5v - 1685 watts @ 4 ohms resistive load

14.4v - 2100 watts @ 4 ohms resistive load

14.4v - 3010 watts @ 5.3 ohms reactive load*

*They used an Audiobahn AW1508X as a reactive load.

Idle current - 1.05 amps

Power consumption - 235 amps unclipped @ 12.5v

THD - 0.014% @ 4 ohms

S/N ratio - 97dB

Frequency response - 10Hz - 50KHz

Damping factor - 900 @ 100Hz

1/3rd power efficiency - 34%

Full power efficiency - 62%

Remember the USA-2000X is only stable down to 4 ohms bridged (2 ohms stereo) whereas the USA-2000 is stable down to 2 ohms bridged and 1 ohm stereo. They're the same amp just but with different settings and sometimes people get that mixed up. The 2000X do not like going lower than its rated impedance and it will happily put up a smoke show through its clear, 1/16" thick and increasingly hard-to-find plexiglass (I had a local shop custom cut me a piece for my 2000X). I would get that repaired and either use it or sell it, they go anywhere from $350 to $500ish on eBay.

The 2000X will tell the BC2000D to get off his lawn.
