No i dont think its that, because if i open the boot, i get good sound. what i have noticed is that there is a thick metal plate underneath the parcel shelf which is trapping the sound from getting through. Almost as if the bass is only in the boot.
I did try taking the back speakers out of the parcel shelf leaving 2 holes going into the boot. this did bring throug some more bass but not really that much.
think i need to remove the metal plate under the parcel shelf, but not sure. dont even no if it does come off, or how to take it off. looks like its bolted or welded on.
anyone got any idea's on how to get rid of this???
