cd-8 bubbler rock-ola jukebox speaker/woofer issue

I just got this jukebox as gift from my dad, he had it hooked up to his house surround system, Im having an issue with getting good sound out of the speakers. And the subwoofer is not giving me anything. Is there a way that possibly the box has a way to turn on/off the woofer or other speakers. Also when I balance the speakers the left speaker has no sound as well just thr right which is makeing poor quality sound come out. Could it be a fuse in the amp? Im lost here, everything else works perfectly and its in brand new condition.

Hi,

The jukebox is all the parts made by Rowe Ami or are they Rock Ola?

What country do you live in?

Its all Rock-Ola and I live in the US. The only thing that is plugged in the top of the amp is the cd input for the cd player, I still have open the cd-output connections, the amp output connections and believe its called the BGM connections. Not sure if I need to add anything to these to get the sound from the speakers. or full quality sound and woofer.
