Hello,
Wired in my GROM audio kit to my 98 S70 T5 SC900 and have some issues present
*there is no CD player module. The tray got stuck, i got angry, it is no longer in the unit. the radio functions fine, cassette still works.

- When selecting CD6 (GROM BT) and raising the volume on the stereo, there is a very loud high pitched whine from the speakers making listening to my sick OEM radio with BT unbearable. I would suspect the upper dash ones are making the noise possibly. I want to keep my OEM radio for aesthetic reasons.

- When playing audio and stopping, ill hear a faint *click*click*click* from the speakers on the right side. This will stop shortly after stopping audio. See Videos Attached of both complaints

Video's here

Im tempted to re ground the Headunit Ground, Amp ground, and GROM Audio ground into the radio cage or chassis somewhere close - good idea? Any tips?

Has anyone had issues like this?

thank you
