one subwoofer louder than other

[vandiar2 10+ year member]

I had 2 12" subs in a sealed box running off of a 1200 watt soundstorm amp (i know its a piece of crap in transition for a better amp). I just bought a new car so I haven't bought the new amp/installed the subs yet. One thing bothered me however when they were in my truck. If you look at the speakers, especially noticeable when the volume is low, one subwoofer is louder than the other!! it is especially noticeable while looking at them, one sub always moved farther out than the other so much that it was very apparent. anyone have any explanation for this? Thanks in advance!

are they the same impedance?

Haha, and the same company / model?

wired the same? example=if they are dula voice coil subs , is one wired in parallel and one wired in series?

good point.

indeed. I know it is weird. both are mtx's, and both are 4ohms. the only thing I can think of is that crappy soundstorm is a 2 channel amp. maybe one channel is outputting more power than the other. both are wired the same as well.

are there 2 gain knobs?

are they DVC subs? or single 4 ohms?

only one gain knob on the amp, and both are SVC 4 ohms. it has me stumped.

is the amp stable bridged to 2 ohms? if so, do that.

or measure the output of each channel of the amp with a DMM

yes I do believe so. but don't get me wrong though, If i bridge a 2 channel amp with 2 4ohms speaker will the amp not see a 1ohm load?

2 4ohm speakers is a 2ohm load

math+you=fail

Are there separate chambers for the speakers?

Is there a hole in one of the chambers?

If you push on the speakers (lightly with no music) does one appear to move easier than the other?

2 ohm bridged mono the amp will see 1 ohm.

maybe swap the wires at the subs so they one briged is reversed?

lol no mathematics is a strong point of mine. what im saying is if you took a 4ohm speaker and bridged it does the amp not "see" a 2 ohm load ?
