Speakers popping with enfig harness

[mdk]

I recently purchased the Enfig SRWH-AUD2-HILO harness for my previously BOSE Symphony II. Overall it sounds great, but I'm getting a significant "pop" in the speakers under the following criteria:

- SAI Pump turns on
- ABS/ESP engaged

I tried putting a filter on the 12V input to the radio, but it's still happening. Has anyone dealt with this or something similar? Any tips?

Thanks in advance.

I'd post in the Stereo section if you haven't already, that way they can see this

FWIW though, no I haven't had this issue with my Enfig kit
