is there a way for you to turn off the speakers and isolate the subs only on your headunit? You can then turn up the volume.

i had the same problem and after and hour of debate, the shop and I have discovered that the volume of the speakers did not match the volume of the subwoofers. Basically the speakers were overpowered. So at volume 1-2 the speakers would be at normal hearing volume but natually the subwoofers cannot sound...this is because normal hearing volume is like around 10-20.

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???

Cheers
