have you thought of making some rear quarter panel cards and puting them in there i reacon theyll fit either side im thinking of trying it with 12" and bringing them out a little with a couple of mdf rings so the back part of the speaker does hit the metal.

yeh thought about that but they really need to be boxed.if i put them in some mdf rear doorcards would there be enough room behind to box them up??
thanks

Did you get a technical data sheet with your subs? Have a look on there and it will say the min. volume you need, then just experiment with different sizes and work out the volumes
(Length x depth x height = XXcm3)

Or alternatively, the blaupunkt (sp) website used to have sub box calculator on it somewhere. have a look see if you can find that.

unfortunatly i din't get anything with the subs as they were second hand.
couldn't find the blaupunkt (sp)website. anyone know the address??
any other suggestions too?
thanks
