I am wondering if my Hifonics ZXI6006
(rated @ 4ohm mono) could be suffering the same situation ie: putting out more power @ 4ohm mono than @ 3ohm or 2 ohm mono....I hooked my dvc sub up paralell for lower ohm load just to test amp and output seems weak.
This was from a test in a magazine....
US AMPS USA2000X
The USA2000X is the only 4-ohm stable amplifier of the group. However, this did nothing to deter the beast from producing impressive numbers. Our in-lab results showed it to be quite powerful, making 1685 watts with 12.5 volts, and a more impressive 2100 watts with the juice increased to 14.4.But placing the USA2000X on a reactive load drastically changed things. Here it took top honors with a very impressive 3010 watts. This is largely due to the 4-ohm impedance design (as opposed to the 2-ohms in the other amplifiers in this test). Therefore, the USA2000X should make more power at the test frequency of 50Hz where the impedance of the speaker rose to 5.3 ohms. In many ways it is fair to say that US Amps had an unfair advantage in our test since the output would likely be higher at this impedance.
Anyone ????
