My car is a dodge charger,my system will consist of 2 12"subwoofers maybe "maybe 15 inch woofers if they fit.my two extra batteries can go in my spare tire area and my amp can be mounted on back of my seat.my woofers will be running off a saz3500,my question is will my setup get way luder if my box ports through the rear deck?or shold i do a box toward the rear of my car with the ports on the side?i dont mind doing a port in my rear deck if its gonna get alot louder that way..

Maybe you should post in the spl/sq section, or try to ask Fishercustoms.
