i have a 1998 caravan 3.0L v6 base model,,,im hooking up a rockford fosgate sound system,,and i cant find a place to get the power wire into the cabin from the battery,,i cant find no holes nothing going inside the car,,any help any suggestionz

 

I just drilled a hole through the firewall. Becareful where you drill your hole so as not to sever any other wiring. Once you have eveything working and in order silicone the hole shut from the inside and outside.

 

I agree with dakota...but if you can try to buy a firewall groument so the wire doesnt rub on the metal and eventually cut into the wire.
