Yup, like I mentioned before, I've DMM measured mine doing right at 3000 RMS to my current subs with gains set appropriately. I have no doubt it benches even higher still, in the right circumstances.
And defying its model number, it's only "rated" at 2500 Watts RMS (comp?).
My current Mmats D3000.1 has been one of my all-time favorite car audio purchases, over 20 Years. One of the most expensive, but still one I've had no regrets for buying. It also takes up as much room as most 1000 W amps. I'm still baffled how they did that and still get such excellent heat control.
Yea, it could be far less expensive to buy a couple amps that can deliver 1500 W RMS each @ your impedance (if your electrical system can deliver that + efficiency loss), since ~1500W amps are MUCH more common.
