I'm trying to get a better look or remove the sub in a '98 Avant...
Haynes manual says remove rear seat base and backs - is this necessary?
would be good to get the sub out to make room for a larger amp for external sub
[bits I have from last car]
(fitted new HU using the wiring adaptor that was already there -
I get 12v feed and 5 to 6v on the signal leads coming out of the adaptor,
but rear speakers and sub do not function.
the HU I removed had the rears and sub working)
