m.a. audio HK-4000D

[Sidebinder]

Item(s) for Sale:

Up for sale is an m.a. audio HK-4000D Amplifier, I don't know if it works and I don't know whats wrong with it. AS-IS. I haven't used it in a long-time, it's been in storage. It is in good shape cosmetically but, needs a new digital display. When I did have it hooked up, it really slammed some 18's.

I am being very clear that I do NOT know if it works as intended or if it will need some work. I am selling it AS-IS!!

Wait, what are you trying to say? Do you want to buy it?

I don't think anyone who has commented wants to buy an untested amp for $400..

 

[Sidebinder]

I don't have anything to test it on. Admittedly, the amp is an older Model. It worked fine for me just it has been sitting in storage for a while. If you would like to make an offer, please PM me. I'm not just going to give away my 4000 Watt m.a. audio, though.

The issue with this amp is they don't work more than they do. They where known smoke machines.

Would you like to make an offer?

If you could prove it works, maybe. If not than it's not worth much.

I could go as low as $390 Shipped, that's a real deal for this kind of Amplifier! Seeing as it goes for $500 or more on eBay without Shipping or Handling, I think you know you're getting a great deal. Anybody who has had decent MA Audio Equipment knows that this Amp was one of their VERY best Competition Series Amps, MA Audio is top of the line!

Top of the line where? Ethiopia?

What kind of electrical did you have?It needs a new digital display.Can't imagine it would be cheap to ship to an amp repair shop on top of the original cost.We aren't trying to crap in your thread.Just helping a little.I'm very familiar with these amps.Running one now as a matter of fact.Got it for 250.00 with bass knob and original box.Not a scratch on it.While i was there i bought his other MA 4k for 150. If these amps are abused or used under 2 ohm it's gonna get smokey.Personally i love em cause there cheap and if ran correctly(2ohm) then they do great.It's your amp and i'm not here to tell you what price to put on it but it's not gonna sell for anywhere close to what you are asking.Good luck and welcome to the forum.
