as long as you set them CORRECTLY, yes.
every time you turn the volume down, the amp puts out less power. with every note in a song, power changes. and due to those factors and others, i wont confuse you with, your subs will likely only see 500w each, at most.
what amp and subs are you getting? make sure the subs are dual 4ohm or dual 1ohm.
The amp is a Massive Audio N4 2000watts at 1 ohm
The subs are 2 dc xl's
