Whats your budget?
Sundown SAZ-2000 will do around 2300-2400 clean and the Cadence iA9 or ZRS-8000D will do 2200-2300 clean (1%thd) and ~2500 (5%thd)..
Last time I checked you need to have the power wire running through the clamp meter to measure amperage.. If you look at the pic both the power and ground go behind the meter.. lol
Once again these guys are full of the brown stuff..
I call BS on these Sound Digital amps...
The 1800w model has only one 80 amp fuse to make their claimed 1800 watts at their claimed 12.6 voltage..
This model would need 140+ amps of fusing if it was 100% efficient..
1800w / 12.6v = 142.85 amps to make power..
I am not sure where you get your info from..
The TX line was in production from 2006-2008 and were made by Cadence.. These amps were introduced online over a year ago and just discontinued as of 2 months ago..

Crappy I think not...
Maybe it cause the sub can only handle 600rms?
Sub specs....
