numbers dont mean anything.... at 20 my deck is quiet, even 35 isn't that loud.

Mine doesnt get loud till 50-60. 61 and 62 are useless because then it just starts to ruin headroom.

0-62 being the range my deck has to work with.

From what I saw, the gains should be slightly lower with your new head unit.

Have you turned the sub on and tried playing with the level, phase (polarity, even though they're not the same... i know...), crossover frequency etc?
