so after i got the hybrids in my vehvile and the zapco 3k i was down to 145.5. so i swapped my old stuff back in and got it up to a 148.3. now im wodering if my older lightening audio amps need less power then my zapco and thats why i was getting smaller numbers? but anyways i wanted to see if people in here saw a increse or decrese from deadening the roof of their vehicles? i got people to sit on my roof before and saw now gains or no losses so i dont know if itd be worth deadening it.

Do you have 2 Zapco amps, or just one ?

What is the nominal impedance on the subs ?

i have one zapco 3k and two lightning audio 3 ks i found i was getting better numbers with the lightning audio amps. but i think thats because i didnt have enough power for the zapco. my aa subs are dual 2 ohm and my hybrids are dual 1 

Thanks!!
