if you're still using that kicker amplifier, make sure that the heatsink is not grounded.
grounding any of the si,ss,zr and xs amplifier chassis, will cause a ground-loop

Do Ground loop oscillators degrade SQ?

I used one for a while, it was a Jensen VBH1RR (http://www.jensen-transformers.com/) and it did the job very well. I would dare say it is the best made... it seemed to soften transients and lowered output in the 150 to 300 Hz region SLIGHTLY. It was very good and I could have lived with it in my system.

(note: I had numerous ground faults and electrical issues at that point, the cars stock stereo had alternator whine prior to this too)
