SOURCE: Bass control stopped working
on rockford amps, the bass control knob needs to be connected to get the maximum output (+18 db gain i believe). If you did this to the power wires, then yes, you may have at least damaged the bass control knob. Try replacing this to see if you get all of your gain back. If not, then you have damaged something inside the amp...maybe a capacitor or power supply inside. If that's the case, you'll need to get the amp looked at by an electronics repair technician or local stereo shop.

SOURCE: amp not turning on
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If neither is too low, the power supply in the amp is probably blown.

When you say that the amp "pops" are you referring to the sound that is coming out of the speakers?
This is most likely the speakers "bottoming out", i.e. moving as much as they can, and then slapping against the back of the speaker frame. Adding the remote bass knob (presumably increasing the signal to the amplifier) would make the problem a bit worse, which explains why the popping increases after you add the bass knob.
You can try decreasing the gain on your amplifier and running the system at a moderate volume. If there's no popping occurring, you can be reasonably sure that the subs/speakers are just being over-driven.
