These are arguebly the best bang for the buck amp ever made. Orion was known for there amazing cheater amps in the 90s and they didnt leave anything behind with the 2500D. These amps are rated as follows:
1 X 1200 @ 4 Ohm
1 X 1700 @ 2 Ohm
1 X 2500 @ 1 Ohm
People have tested there amps to push out closer to 2700-2800 at 1ohm.
Also on strong electrical these amps can run .5ohms.
I have had 4 and loved them, never had any issues with any of them. I find them very efficient and reliable.
