My SVS subwoofer will not turn on from auto mode

I have a small(9 by 10) room and installed a new SVS SB 12 subwoofer into a 7.1 system.Problem is my Yamaha receiver does not seem to wake up my sub from auto mode.Since room is small and in a 2nd floor condo I cant run the sub very loud so gain is in 10 o'clock position. SVS said I should keep sub gain at 1 o'clock position but that is too loud for my condo.Any trick to getting the sub to turn on from auto mode without loud volume setting?

SVS told me that Yamaha receivers have a low bass signal so I may just have to wake them up manually.It seems that cds played on my Oppo DVD player don't wake  it up. With dvds it seems to wake up sometimes. Im going to buy a dedicated subwoofer cable to see if that helps.  Thanks for your help

Just ordered some Blue Jeans LC-1 sub cable off Amazon.  Flexible, well shielded and affordable.  Have been using some unshielded interconnects.  Figured it was about time to do things right.  You can always spend way more than the BJC, but why?

1. Try a 'Y' rca cable connect the receiver LFE to both L/R line input on the sub, if made no difference then
 
2. If your AV Receiver has pre-out and you have a pair full range front main speaker, you can try connect the sub line input to the receiver front L/R pre-out, and re-configure the receiver setup to full range main L/R speakers, select ’No sub’ for the LFE channel, set the subwoofer internal low pass filter to 80Hz or lower. Hopefully the stereo full range pre-out signal will wake up the sub easier.
