ddm reading

so i checked with my ddm on my system

playing a -3db beat at volume 39/50 ,
my amp is reading like 50.4 volts,
and when im playing songs, its ranging from 20-45 volts. ..

is this okay for a rockford fosgate 1500 1bd and 2 sa 12s? or am i overpowering them?
the gain is about 5, infrasonic filter on, ported box.
d4s wired to 1ohm
4awg, 100A fuse(atm) upgrading to 0awg later.
it sounds just fine.. my voltage on my battery is stayin above 12.4 aswell.
but is this bad for my subs?

thanks!

Without an amperage reading or at least an impedance guess:

Do they pop or make other funny noises?

Do they smoke or smell?

After hammering on it for a bit, is the dustcap hot?

If no, then it's fine.
