Probably thinking Lanzar would live up to the hype. (As you know now, they do not)
Sorry to be so blunt, but them's da facts and those who have been in this game a while, don't even look at peak power numbers. We look at RMS or "Continous Power" specs for the real details.
Look at the fuses on this amp and the power cable/ground connects. They should be #4 gage power lines at the very minimum. Even that is too small.
As for power ratings, if this amp is bridged MONO, it might deliver about 1200 watts RMS to a 4 ohm sub. However, it's a 2 channel, Class A/B amp too. This type of amp wastes a lot of power due to heat. Class A/B amps are ~60% efficient. They lose 40% of power consumed to heat. If not fused to ~200 A's, this amp is not even close to stated power.
Read this series of posts and treads. They seem to have a few right-minded people answering the guy's questions.

In a nutshell, one get what we pay for. Branded names are more honest as they know the consumers are shelling out more $$$ and expect more than vanilla ice cream.
Finally, I'm not saying all Lanzar products are trash. The older series Opti-Drives were solid amps in their day. However, always remember this... "Figures don't lie... but liars can figure". That may well be the issue you are dealing with now.
