try disconnecting your RCA cables to the amp and see if it make noise with out them on. then try with the motor running. if there is no noise then it your RCA cable are bad or dont have a good ground from the stereo.

and if it make noises with the rca cable disconnect mostly like a ground issue

like i said, before if it stop making noise with out the RCA cable disconnect, it mostly like rca have bad ground from the stereo. you can try doing this to your stereo and it should work..

If grounding them out dosen't help it could be that RCA cables are picking up the sound of the electrical current running through the power wire. The signal picked up and added to the RCA wires signals is emitted as a constant "hummmmmm" through the subwoofers.

if the problem is still there with out the rca connect. then i will look into your gain setting. if your LEVEL is too high up. it will pick up any little vibration from the motor or anything.

i would try setting the level all the way down nd if the "hmmm" goes away. then try hook back up the rcas if it still come back. try running new rca but dont install them. just run from the head unit back to the amp, and if there is no "hmm" then install those new rca and like said above route the far away from your power wires.

- also if you screw an amp down to metal (car body) some amp will pick up ground noise. and cause a "hMMMMMM sound"
