Speaker vibration?

I just installed my PA RZ4-2000D amp in my 15 SG using the BT line lever. I'm getting bass vibration in the fairing and lowers. I have BT 7.1's in the fairing and the newer kickers in the lowers. Will polyfill help out or do I need to adjust gains?( I left the gains on the same settings when I had the RZ4 on my 07 Street glide) I have the BT Brackets for the 7.1's, so the pods have been removed. I was thinking about rapping the speakers with polyfill if it will help.

Please advise!
Thanks,
Brian

Do I or can I still use some of the polyfill?
Thanks,

On my 7.1pro's I used one thin layer, then two layers and I'm tuning the systems now. After I'm satisfied I will remove to see if I hear a difference. Wanted to stop vibration / resonance.

Brian, what method did you use to set the gains last time, by ear, or DMM?

I did not set the gains for the 2015SG. I left it with the same settings I had when the razor amp was in my 07 street glide connected to the HU. Didn't even think about it. I guess I was so excited about getting the BT line leveler. Should I try setting gains by ear?

Thanks,
Brian
