I have this amp running running 2 12 kicker cvr's in a ported box at 2 ohms giving them 1000rms. It just may put out the stated power. Im getting rid of the cvrs and getting a single RE sxx 12 and going one ohm. Then ill be able to see if its putting out rated power because my friend has a RE sxx at one ohm on a Rockford T1500.1bd (which is obviosuly a better amp) but I want to see in comparison how the onyx 1500.1 goes up against it for way more than half the price of the rockford amp.
