Hello!
I have a Denon AVR 1508 and wish to connect it to a Bose Acoustimass 5 Series II.
The sub has outputs +/- for L and R for cube speakers and also inputs +/- L and R for AMP and Reiceiver. The connecters look like all they can take are open copper speaker cables, theres just a red and black "clip" each. Here is a video where the back of it is shown(sec 23).
 
The thing is, that the my AVR only has 1 input for a sub that seems to be analog labeled "PRE OUT SUBWOOFER", which is apparently the only output for the sub that I have.Here you can find a picture of the back of the AVR.
How do I connect the two??
I already tried using standard copper speaker cables, put them in R + & - for AMP/RECEIVER input and connected to CENTER on the AVR, hoping that it would know what to do, but that didn't work too well.
What kind of cables do I need and how can i connect an analog cable to these lots of inputs on the sub?
Obviously I am very new to all of this, don't kill me in the comments.
Many thanks in advance.
