Hi,

I'm going to be fitting Pioneer 13 cm 250 W 3 Way Coaxial Speaker System into my take up, it's the model with windey windows, we've had a go at getting the door card off today with almost success but we believe there is a nut or some sort on the bottom of the door card, has anyone got any advice and what screws will I need?

Thanks

you just need to turn it 90 degrees with a small adjustable spanner
