After bumping Hix's 3000d and mentioning Orion 2500Ds, I will also mention my Stetsom 2k6d. I have not benched it because I don't have the equipment. That said these are the ratings from Stetsom:
RMS Power @ 13.8V
Mono 4 Ohms: 2200 Watts
Mono 8 Ohms: 1200 Watts
RMS Power @ 12.6V
Mono 4 Ohms: 2150 Watts
Mono 8 Ohms: 1050 Watts
Minimal Input Impedance: 0,2V
Total Harmonic Distortion:
Signal to Noise: > 90 dB
Crossover Frequency LOW PASS: 50 to 15 KHz
Frequency Response: (FULL RANGE) 20 Hz to 15 KHz (-3dB)
Input Tension: 9 to 16V
Power Consumption: 3,3 to 240 A
Dimensions : 70 x 280 x 330 mm
I am running it right now at 0.5 ohm daily, so I know it will handle 1 ohm, but I have no idea how much power you will get. My guess? Somewhere between 3kw and 3.5kw on a solid electrical. It's not really for sale, but considering your budget I may be willing to redo my system....again.
