Hi - I just purchased the RD-6502 today and am presently plugging in my VCR and DVD, etc. I previously had a Pioneer DVD Home Theatre system which had its owb speakers and subwoofer (unpowered). The speakers work fine on the RD-6502 but can I use the unpowered subwoofer and where do I connect its connector wires? Also are there any diagrams of typical setups for these A/V Receivers on the wen? Thanks for any advice Steve
