I used a jig saw with a fine tooth metal cutting blade. For the deadening I took two strips of material(one smaller than the other) and sandwiched them together(sticky side to sticky side) being careful to leave about 3/4" of an inch of adhesive exposed on the edges and just stuck it over them. The crossovers were under the carpet mounted just below the HVAC/blower motor.Also, what did you use to cut your doors to fit your Hertz? And how did you sound dampen over the two bars that open and lock/unlock the door without causing them to stick?
