New AMP, speakers whistle when on throttle

So my Bimmertech amp woes continue. I now get a whistle that sounds almost hilarious when on the gas. Confusingly, it only started happening after I installed the Technic PnP ASP Bypass Cable. The cable got rid of the weird static I normally heard when on the gas but now I get this whistle.

Any ideas??


FYI - Seriously thinking of going back to stock HK system and selling AMP and Bavsound. Truly not worth the trouble for what is, at best a marginal improvement in sound.

Seems like it's the harness. Email Technic.

From my older audio days I would say there's a grounding issue somewhere.

This! From my days working in the car audio field I can almost assure you that a grounding wire issue the culprit here.
Any halfway decent audio shop should be able to straighten this out for you.
