RE: Dual 10"
i looked in my dads trunk, if u wanted,u could prob use the oem box,and put a wooden face plate to cover the side,so when u built a box on the other side,it will match.
the oem box has the amp built it in and its a "kicker custom" ,which more than likely means that its a special low grade kicker sub made for dodge.
if u stick with the oem and add a new one u will still have to get a new amp...your choice.
also...a thank you reply or question reply would be nice.
