Hello... When I got my TJ the PO already added an amp and speakers, subwoofers and stuff... So when I was looking into the dash speakers (cause the sound is almost none) I found this little black box and this kind of pod... Do you guys know what is the intention of the black box? I unplugged it and nothing happened.. The pod I will be removing it because I want some polk audio 5.25 to sound louder and better.. But.. I see that the wiring is not like a normal speaker... Can I just trim the wire of the conector and plug it into a normal speaker? Thanks..
