reason i ask is cause i just got a bass cd with the test tones and set my amp with a dmm, and turned my gain from full to half...not as loud, but atleast now i won't blow my subs.
set by ear, and figure perfect world settings zx2500 is underrated but just take the birthsheer say if it does 2700 watts at 14.4 then divide that and times it by say 12 volts which would be 2250 if the voltage is at a contast 12 volts
