yeah thats basicly exactly what my box looked like for my L7's....it just had 2 seperate ports.
but that kind of work is WAYY beyond my skill level, im a master at wiring...but box building i dont mess with yet....i just ordered a premade box from online for my old subs, i didnt build one.
if i just bought a box from online for 2 12" round subs would that work just as good?
