Greetings,
I just have a quick question regarding the jPac and wiring the speaker connections from a jamma harness. I've tried searching the faq, but no avail.. 

I've decided to use the speaker hack, and wire the existing cab speaker to a torn apart set of creative's ... my question is this .... Since I'm using the speaker hack to generate sound, will I still need to use the speaker + & -  wires form the jamma harness and connect to the jPac?   ( i hope that makes sense )  

Thanks in advance for your help.
Michael
