Yamaha RX-V1200 subwoofer connection to Mirage BPS-150i subwoofer
My Yamaha RX-V1200 receiver has a single jack for a sub woofer out. The Mirage BPS 150i subwoofer has a 4 RCA connection, a mono input and a crossover input. The Mirage manual is confusing me as the diagram depicts a 4 RCA connection. Is there such a cable as a 4 RCA into one ?? Any help would be greatly appreciated.. thanks.. Bob, Lawrenceville, GA

Re: Yamaha RX-V1200 subwoofer connection to Mirage...
Just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out

Yes you can modify RCA cables to make bare wire tails. If the unit has a sub o/p then you just connect up your sub bass unit to whatever the amp needs.
An RCA cable is 2 wire which is all you would normally need for sub bass speaker level signal. It may be a good idea to eventually upgrade the wire size if you want really good sub bass as lower frequencies draw more current and so require more copper.

Your receiver should have an RCA connector on the back panel that will be marked "sub woofer" or "LFE out". That connects to your sub woofer with a standard RCA type cable. Also, some powered subs have left and right speaker level inputs and outputs in which you would indeed run the sub woofer through the speaker outputs. The down side of that type of connection is that the line level converter inside the sub woofer will take a slight amount of your receiver's output power, although that is rarely detectable. Also, if you have a Dolby Digital receiver, using this connection method will take away systems ability to accurately control the low frequency effects of a soundtrack.
Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.
Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.
