is this normal?

Did you possibly have the dmm on the wrong settings? I'd say find a step by step guide to setting a gain with a dmm Even if you think you know how. And start at 1 and move along, see what happens. Gotta be something simple.

Also with that new box, maybe your not used to the flatter response. Was your old box very peaky?

i did follow a step by step guide, multiple in fact. and my old box was a prefab box so it was probably tuned somewhere in the 40's

Do you have a sub control option op?
Also if your hu is 2v preouts your gain may need to be higher or you need a larger amp. I'd set the bass at 0 and figure out the problem with your dmm and go for target volts.

HU preamp voltage is 4v

Maybe the dmm is bad? Also check impedience load of the subs, make sure you got the load your looking for.
