One woofer moving more than the other

Are both subs equal distance in all aspects to the port mouth in the box? if they are staggered you may have an unloading issue...

I'll try swapping the wires from the amps, if the same sub is doing still doing it, I'll take it out and inspect it.

By the way, their isn't a huge difference is movement, but its noticeable by eye.

One thing that I find dumb is that with the gains matched at 47.9, one amp is gain half up, the other is about 3/4.

Out of phase?

These amps don't have a phase switch.

This... I had a bit of problems with my rear sub trying to unload on me... but switching and putting the slightly less powerful on the farther sub fixed the problem...

edit: Nevermind I see they are equidistant...

this one got me thinkin. id check the ohm loads coming from the box just to check it off the list and then id start looking at the amps. any weird sounds too? im learnin too so dont hate lol just an idea(what i would try first)

I would check the ohms on each sub and make sure nothing looks odd with each driver. Then flip flop the amps. If the same sub is acting odd then you know its not an amp problem and more of a sub problem.

Obviously the gains aren't matched if one amp is up 3/4 and the other 1/2... If they're the exact same amp then you have some sort of wiring problem. Could possibly be the RCAs going to the one amp..maybe they're going bad and the preamp voltage is low?

There is one rca coming from the sub out on the alpine going to the back, then they are split with a y-adapter. Daisey chaining them seems to only work when strapped.

Is there a way to measure the ohm load coming from the speaker wire with a DMM?
