Yes the car is fitted with a HK system which comprised of HK logo'd front door tweeter covers but totally standard speakers in all doors !
There was a powered amp plus two base drivers in the boot chamber but they have been removed due to water damage .I'm surprised that there would be two power amps though but I'll remove and examine the unit and see if the wiring matches up with the loom in the boot.
Thanks
Mine is an 03 Premium. At some stage they integrated the sub amp into the main one as all there is the boot locker is a dual voicecoil speaker in an extended case and no amp.
Details in the Rave manuals are extremely limited.
