F/U: best way to wire my Yamaha sub (1 Viewer)

[Bo-Cephus]

Thanks Bob for your help. I have one more question. It appears the "Input 1" of my Yamaha sub has only inputs from speaker outputs ("L/R") with no RCA jacks. The "input 2" has 2 RCA jacks, 1 "L" and 1 "R". If I use an RCA subwoofer cable to connect to the sub, should I use the "Input 2", and if so, connect directly to either the L or R, or get a splitter to connect to both? Thanks again for your help (or any others).

You should connect to the RCA jacks for "Input 2".

Now in theory - you can hook into either L or R because they sum together inside. And a 1.0 volt signal into 1 jack if split becomes two 0.5 volt signals that sum back to 1.0 volts.

But many members have reported liking the sound better if they use a "Y" adaptor and plug into both jacks. (I suspect this is because hooking something into that other RCA jack reduces noise).

So the general consensus is use a "Y" splitter and fill both jacks.

Hope this helps.
