Ok, hello everyone i am new to car audio, i basically been working under hoods of cars and just recently got into car audio. Here is my question..I have a box for 2 12 inch subs. I have 1 12 inch kicker l7 in there right now. I am getting another one soon. The box is not ported. One of my friends are telling me that my box is going to fall apart? is this true? here is a picture of the box in my car.
i have 1 l7 in there now. is the box bad for 2 12 inch kicker l7s?
number 2. what kind of amp do i need to power these two subs?
and will i need a seperate battery?
