In case you didn't know, you may have Dynaudio drivers in the car; they
don't come much finer than that!
So you have speakers behind the rear seat, then there should be a switch on
the center console facing the back seats to turn them off, if you so desire.
The speakers behind the seats would be dual woofers in addition to the
drivers in the rear side panels. The C70 has one of the finest oem systems
ever installed, anywhere. Look in your trunk, fiddling with some of the
panels you might be able to see the backs of the "subs" and get a part#. It
will likely be labeled Volvo Dynaudio. Also, if there should be an
auxilliary amp (located in the trunk towards the rear driver's side behind
the cover panels). Drop me an email at p s h
and I will send you some detailed volvo product literature from that era.
