Other than the possibility of having a bad speaker, is there anything else that could be messed up that could cause a speaker to make that popping sound when the bass hits.I tried a different speaker and it did the same thing and i know the other speaker is good.

and if the amp is turned down low so there isnt too much power

Very likely, (since you ruled out speaker defects,) your amplifier is "CLIPPING"
Clipping is what happens when the signal in an amplifier is too large and the driver transistors "run out of voltage" from their power supply. So the voltage waveform goes up to the max it can go, and then it stops increasing, giving the waveform a "flat" or "clipped" top. We hear this form of DISTORTION as a kind of popping sound.
You can check for this with an OSCILLOSCOPE, and look at the waveform being sent to your speaker. If the amp IS clipping, it will show up clearly on the scope.
If this is a condition that suddenly appeared in a system that was working properly, it indicates a fault in the amplifier; possibly too low a power supply voltage. Other faults could exist in the amp also.
I just noticed your additional comment about having generally low power at lower volumes. Aside from a defect in your sub woofer amp, (possible) you should be sure speaker impedance (ohms) are within the manufacturer's specs, because a mismatch can cause this also.

I've seen that issue with a poorly sealed box, where air is escaping around the edges of the subwoofer, through the screw holes or even the seams of the box. Make sure the box is well sealed. Use weatherstripping material or non-hardening strip-caulk to seal the edge of the subwoofer where it's screwed down to the box.

TO MUCH POWER
THE SPEAKER BOX IS TO BIG FOR THE SPEAKER OR IS LEAKING AIR
or your amplifier is sending cd voltage to the spaaker making it travel to much in or out
sorry for the caps

It feels like there is a few thing the two interfering with it, that could be an applianced plugged into the comparable circuit, or extra in all probability the flexibility grant interior the sub is going undesirable.

too much wattage to the speaker could cause that and will damage it
