It is in a KC, bought the L7's new. It has been installed about 3 months, hits in the upper 130's to low 140's, no one around me has a meter. I have 2 Orion 225's on them pushing 400 watts to each sub.
I am talking to a guy with a ported RE set up i am going to get if we can set up a meeting, i will set a price after i see how much it would cost to ship, the box and subs are heavy.
