**Advice needed** Am I going to damage my sub with this amp??

[KcContractor]

I do not know why those users would warn about a little more power. You can set the Gain low to put out the power you need. The formula is A/C Volts = Square Root of (Watts x Ohms). In your case you want to give the sub 750 watts, the sub is 3 Ohms. 750x3 = 2,250. Square Root of 2,250 = 47.43.
Connect your multimeter to the amp's sub output (no sub), set multi to AC Volts, turn gain up until you get 47 Volts.

Thank you!
