Quick Wharfedale SW150 connection help please!


Established Member
I there. I've recently upgraded my amp to a Yamaha 861 and have also had to move my sub across the room. I've bought a 10m rca to rca cable to connect up without realising there is no single rca input on the back of the sub.
I guess i need to buy some sort of adaptor, but do i plug into the left or right sub input??

Any help is grealty appreciated :thumbsup:

No, no need for an adaptor. A lot of subs are built like this.....I think you can use either, but most manuals i've seen usually say, use the "right".

Hope this helps.

It doesn't matter - you'll simply get 1/2 the sound volume out for any particular input level, as the 2 RCA inputs are normally simply summed together.

I use one of these:-

IXOS XHA215-Y1F Subwoofer Y Splitter / Adapter (0.3m)

which Richersounds were selling ridiculously cheaply, but don't seem to stock now.

Just remember to re-run Auto Setup again when you've connected both inputs !

You don't need any adaptors, as prize said just use the right RCA connector (you'll probably find such advice in your sub's manual).

Cheers everyone, so i'll just plug into the left white (or red?) and run setup on the amp.
I guess i'll just give it a go then!
