Pac tato/pioneer z150bh HELP!!!

Hey guys so I bought a pioneer z150bh and i installed it with my pac tato. Unfortunately it seems like I have no base, and the quality of sound kinda went down. Does anybody know why this might be?

 

*bass not base.

I'm assuming you have the JBL system, does the sub turn on at all?

Have you tried adjusting the HU subwoofer settings.

 

Ya it turns on but i get more bass from the front then the back sub. I tried messing with it and it seems better but not what it used to be like.

Sorry mind lapse on the base-bass

 

got it working.... had to mess around with it. but i am confused on what this wire does? doesnt seem to fit anywhere. Came with the pac tato

 

can anyone chime in on his last question or a how to for this instal pac tato? im having issues with it now. not 100% sure how to wire it all up.
