<font color='#000000'>Please help! My house is prewired so that that the subwoofer recieves 8 wires ( 4 left and 4 right). My problem is that I bought a new A/V receiver and it only has one RCA jack for the subwoofer out. What can I do? Are there adapters to convert the 8 wires down to one RCA? Can i buy a small amp for the subwoofer that has eight conections and connect that to the A/V receiver? Any ideas would be appreciated. Rewiring isn't really a practical option. Thanks</font>
