I'm new to the SS product line and the SS forums so I'm sure this is a stupid question. I want to a single RL-p 12" for my wifes car and it would be great if I could use her old prefab box.So the big question is...... Will it work??? Here are the specs: 2.18 cubic feet tuned to 40 Hertz ports are 25.00 square inches. Thanks in advance!!!
