Subwoofer in Overland WJ Please Help
Im loooking to install a subwoofer into my 2003 Jeep Grand Cherokee Wj Overland, which has the infinity sound system. I have the stock nav head unit and would like to keep it. There is already a stock amp and the speakers on the front doors are considered subwoofers but I think another amp may be needed. Can some please walk me through the process and adding a sub to my sound system and the cables and parts I will need?
