With the new system which is the loudest i have had in my truck, a lot of rattling has been rooted out, but much still remains. In my ext cab, the side windows on peakier notes like to slap and it is quite loud, enough to hear over full tilt and really dont know what to do to prevent it. Expanding foam did wonders on the rear side panels along with 80mil and padding. still doing to do a "air guide" so to speak directing the side firing port to the back of the drivers seat and off one of the side windows/side of the truck, and do a trim panel on the passenger side hoping to seal off the lower panel from compression and air movement.
any advice from truck users would be great.
system: 2 XL 15s, 4krms. peakiest notes are from 27hz-35hz.
