Alan,
Apreciate your thoughts. I need a more detailed explaination of the requred connections. Sorry for the ignorance. The PC 90 sub has rt & lft inputs & outputs & a high pass toggle switch 0db & -03db. The Crown 300A has reostat controlls fro Rt & Lft .
I connnected the rt & Lft to the Crown pre amp and an RCa from the Aux LFT to the sub out on my HK 7300 receiver. Power cord from 300A to pre amp inswitched and pre amp to HK switched. Connected the 300A to the sub Rt& Lft inputs. don't know what to do with the sub outs. hear nothing and feel nothing form the sub driver. What have I done wrong or not done? Plan to get the 500 Axiom sub but will do 2 pair of Axiom surrounds first so would like to use the PC 90 for a while. Thanks again for any help.
Gary
