Crown micro tech 1000 ?????

Are these amps any good for running subs. I have a chance to buy two for $250.00. Want to use them one each for a pair of Dayton RS18's

There are some that are still working?

Every one I saw (back in the day) was burnt up pretty good-beyond reasonable repair.

They were not on the market long-before they were replaced for the MT1200. I guess for obvious reasons.

The Micro and Macro tech amps were very good for subs-but I have never seen a MT1000 working to get an opinion on it.

I have one in my amp collection-but of course it does not work.

I would assume that if they are still working-they don't have the issues that the original ones had. Maybe they have been "fixed up" a bit.

The guy also has a crown macrotech 2400. Is this a good amp??

Assuming they are working, the two micro tech's would be the better buy.
1000watts RMS x2 vs 800watts RMS x2 @ 4

You'll need two 15amp or one 20amp circuit though to see those numbers...

These are old-school amps. RMS Power for days, but very inefficient. As you can see at the end of this video, it's bigger brother the MT5000 can produce enough power to heat the water-heater coils he has.

Yes they are working. I have a couple of xls1000 amps bridged. They run out gas below 20HZ. How would two micrtech 1000's stack up against the xls1000's???? Also the manual on the macrotech 2400 gives 2 ohm in bridged mode. I think it's over 2000 watts. Could I run both subs off that one amp in 2 ohm??

I used to run a lot of MA2400s on my rental PA. I have never seen any spec that is 2 ohm bridged. Can you post a link?

Without knowing anything else-as far as detailed specs and no personal experience, but I would take the MT1000s over the XLS-as a guess. The MTs are pro amps-the XlS not so much.

However a lot has changed over the years-and the older amps may not be "as I remember".

Without know the impedance of your subs-there is no way of guessing how many you may or may not be able to run off of any amplifier.

The specs are in the manual off the crown discontinued section. The subs are 4 ohm Dayton audio 18's. http://www.crownaudio.com/media/pdf/legacy/130252.pdf

Oh, you already have two bridged amps? In that case, it sounds like you need an nu6000DSP. That gives you about 3x the power or about 4db extra SPL.

MT1k is -1db @ 10hz (the XLS is probably -3db @ 20hz, guessing); so it would be a bit better, but it's more of a side-grade than a real upgrade.

I have looked at the inuke 6000 looked to be a good amp!! I am also looking at the peavey ipr2 5000 and 7500. Looks like those have been getting good reviews and a lot better looking the inuke.

What are the actual numbers per channel on the inuke?? I don't think it is really 3000 watts x 2 into 4 ohms
