ok audio ima put something in perspective to you. These are the amps I have used in the last 5 years that I have been competing all tested the same way with my results.
ddz2=11,900 watts
rd audio 9.0=9800 watts
ia40.1=8800 watts
ab 500.1=8900 watts
ab 200.1=6600 watts
treo 4.1=7200 watts
ab xd3000=5600 watts
ab 400.1=6900 watts
mmats 3000.05=4200 watts
catus pf600.1=8400 watts
ddz1=6200 watts
ddm3=4600 watts
as you can see I have tested alot of amps some big some small, and for the 600.1 being able to keep up with the 40.1/500.1/400.1 its a testimate to the cactus. No matter how you look at it if I use peak hold its a referance to see if whats im doing gaind power on the output, and 4 world titles in 6 year after the first of january I am doing something right, and im not changing anything just because you dont like it.
z2 is the strongest amp I have ever tested
