Get your manual handy or download from the above link.....
Then go to page 11, with your HU is on "off", try to get the below option :
SUB/REAR*1
To switch the audio output.
– “SUB-OUT” (z): to output to a subwoofer.
– “REAR-OUT”: to output to a power amplifier.
Make sure it is on "REAR-OUT"....
Then see how it goes....

Hmm, update us on the performance feedback.

Njoy your HK trip ..
If you can make it on next Sunday also better...... But after knowing you work in Lowyat Plaza, it will be easier for me to look for you as I go there quite often..... Almost go there once every 2 months....
