sub help

i hooked up my subs and everything worked. but when i turn the amp on, one sub will push outwards then go back to where its supposted to be. but the other sub will just move alittle and go back where its supposted to. its not moving outwards like the other sub. but when i play music, both subs still work and play out bass. whats wrong?

are you sure the one that doesnt move as much isnt out of phase?

What type of box do you have? Are the subs the same? wiring to the amp similar? HU settings not set to the left or right?

whats it mean when a sub is out of phase?

i have a sealed box, subs are the same, wiring is the same, HU is set correctly.

positive hooked to negative, negative hooked to positive

yes make sure the (+) on the Amp is hooked to the (+) on the sub abd the (-) to the (-) and what not.
