I have an Onkyo SR707 receiver and a Polk Audio subwoofer. There are two (RCA?) connections, both purple, for the subwoofer output on the receiver and two (L and R) inputs on the subwoofer. Help!

Just use one and pick either red or white on the sub...


You "could" hook up both to both(red/white), but it would be redundant.

OK, but what about the receiver? One or both? Which one?

 

[trumbull247]

Makes no difference.


Pick one on each end.

 

[diggerwolf]

OK thanks for the help.


I'll try it but I wonder why is the an L and R if it doesn't matter?

 

[trumbull247]

Makes no difference.


Pick one on each end.


The R/L would matter if you were using a receiver with pre-outs(like the HK 3490) and running left and right to the subwoofer...


You aren't doing that cause .1 is already mono.


.1 times 2 is redundant.

According to an owner's manual for Polk subs, the L+R line-level inputs are for...

Receivers with full-range (unfiltered) Left and Right “Pre Out” jacks (this is the least commonly used hookup).


• Connect the left and right preamp output from your receiver to the left and right LINE LEVEL input of the subwoofer ...

In your situation, and as indicated by trumbull247, run a coaxial (RCA-to-RCA) cable from one of your AVR's two subwoofer outputs to the L or R input - or, using a Y-splitter, to the L+R inputs - on your subwoofer.

Excellent. Thanks. Ordering the cable now from Monoprice. I'll report back with the results.

Once you get the cable don't forget to turn down the sub volume as it's set to max in your pic above.
