amp help

[reg93f150]

i know asking this is probably gonna get me raged at on here because the owner of the forums sells something to do this haha, but for me and my case i feel that it would simply be a waiste of money for me to buy the distortion detector just for my one system, ive got everything done the box, subs, wiring, battery, now i just need my amp tuned for my subs..

the amp is a concept cd-2410 running at 1 ohm

the subs are kicker compvx dvc 4 ohm running at 1 ohm (750 rms, 1500 peak)

ive been reading that i get true output of my amp and times it by the ohms then get the square root of true output x ohms

then match that on a basic multimeter while messing with the frequency and gain knobs, if so can anyone else give me some imput on anything else i can do to make it better and make sure im not getting a clipping signal or distortion? any and all help, i appreiciate so much for reading this and taking your time to explain it to me, thanks.

at 2100 watts:45.83

at 2200 watts:46.90
