I currently have a single 10" kicker L7 in a ported box with 2.25 cubic feet tuned to 38 hertz. I was thinking of making another hole in there and stick another L7 in it. Would this be a bad idea? if so why?
This would probably not be a good idea at all because whenever you have more then 1 sub in a box you always want to seperate the chambers. However if you were to do this and you took the box apart, you could also the size of the port and then also add another port to the other side. But if you cant or dont know how to do that then its probably not a good idea.
