I have a dual 2-ohm memphis mojo and a memphis pr 1.1000 amp, im 99% sure that I used to have it hooked up at 1 ohm, but now when I hook it up (according to the12volt diagram) it loses power (barely moves at all) and I also tried 4 ohm. the only way it "works" is with ONE voice coil hooked up, either one, just not both, what could be the issue here?

Switch the wires around on only one of the coils.

Ive seen Memphis stuff in the past come with the terminals marked incorrectly. You can use a 12volt battery to check the correct polarity. connect each wire from the coils one at a time to the batteries + & - terminals. If the positive is correctly marked the sub will jump outwards when touched to the the positive of the battery. If it jumps inward, the polarity is incorrect
